Balochistan became a province in 1970 after administrative reforms. Thus correct is 1970.

The Paris Climate Conference, officially known as COP21, was held in 2015 in Paris, France. It brought together representatives from nearly every country to address the growing threat of climate change. The conference resulted in the historic Paris Agreement, a global pact aimed at limiting the rise in average global temperatures to well below 2°C above pre-industrial levels, with efforts to restrict it to 1.5°C. This agreement is significant because it marked the first time that both developed and developing nations committed to reducing greenhouse gas emissions. Countries pledged to set nationally determined contributions (NDCs), which outline their climate action plans. The agreement also includes mechanisms for monitoring progress and providing financial support to developing nations. The other options are incorrect because the Paris Agreement was specifically finalized in 2015. The year 2016 is associated with the agreement entering into force, not its negotiation. Understanding the timeline of global environmental agreements is important in competitive exams and helps in building awareness of international cooperation. Therefore, 2015 is the correct answer as it represents a milestone in climate diplomacy and global environmental governance.

Attock Fort was built by the Mughal Emperor Akbar in 1581. It is located near the Indus River in present-day Pakistan and was constructed for strategic military purposes. The fort played a crucial role in defending the northwestern frontier of the Mughal Empire against invasions from Central Asia. Akbar was known for strengthening the empire through administrative reforms and military infrastructure. Attock Fort was part of his broader strategy to secure trade routes and maintain control over key regions. Babur founded the Mughal Empire but did not build this fort. Sher Shah Suri was known for road construction, including the Grand Trunk Road, while Aurangzeb ruled later and did not construct Attock Fort. Thus, Akbar is the correct answer. The fort remains an important historical and architectural landmark in Pakistan today.

Max Planck, a German physicist, is known as the father of quantum theory. In 1900, he proposed that energy is emitted in discrete packets called quanta, rather than continuously. This idea explained blackbody radiation, which classical physics could not. Quantum theory revolutionized physics and led to the development of quantum mechanics. It explains the behavior of particles at atomic and subatomic levels and forms the basis of modern technologies like semiconductors and lasers. Gravitational theory is associated with Isaac Newton, while the theory of relativity was developed by Albert Einstein. “Quality theory” is not a scientific concept. Thus, the correct answer is quantum theory. Planck’s work marked the beginning of modern physics.

Ethiopia experienced a severe famine during 1983–1985, which became one of the most well-known humanitarian crises of the 20th century. It was caused by a combination of drought, political instability, and poor agricultural policies. The famine led to widespread starvation and the deaths of hundreds of thousands of people. It also triggered global humanitarian efforts, including aid campaigns and awareness programs. This event highlighted the importance of food security, disaster management, and international cooperation in addressing crises. Other periods listed are incorrect for this major famine. Thus, 1983–1985 is the correct answer, representing a significant historical event in global humanitarian efforts.
