Explanation: The Salarjung Museum in Hyderabad is a significant cultural institution known for its extensive collection of artefacts. It houses a vast array of items, including sculptures, paintings, and decorative arts from various periods and cultures. This makes the first statement true.
Kolkata and Hyderabad are both metropolitan cities in India. A metropolitan city is a large urban area that is a significant economic and cultural center. Both cities are known for their historical significance, cultural diversity, and economic importance, making the second statement true.
Aurora kinase, however, is not responsible for antioxidant action. Aurora kinases are a family of serine/threonine kinases that play a crucial role in cell division. They are involved in the regulation of the cell cycle, particularly in the processes of mitosis and meiosis. Antioxidant action, on the other hand, is typically associated with molecules or enzymes that protect cells from oxidative damage caused by free radicals. Examples of such antioxidants include superoxide dismutase, catalase, and glutathione peroxidase. Therefore, the third statement is false.
In summary, the correct answer is (A) Only 1, 2, as the Salarjung Museum in Hyderabad is indeed famous for its priceless artefacts, and both Kolkata and Hyderabad are recognized as metropolitan cities in India. Aurora kinase, however, is not responsible for antioxidant action, making the third statement incorrect.
