Explanations:The question involves evaluating the truthfulness of three statements related to cultural landmarks, metropolitan cities, and biological functions. Let's break down each statement:
1. "Salarjung Museum in Hyderabad famous for its priceless artefacts." This statement is true. The Salarjung Museum in Hyderabad is one of the largest museums in India and is renowned for its vast collection of priceless artifacts, including paintings, sculptures, and decorative arts from various cultures and historical periods.
2. "Kolkata and Hyderabad are metropolitan cities of India." This statement is also true. Both Kolkata and Hyderabad are officially recognized as metropolitan cities in India. They are large urban centers with significant economic, cultural, and political importance. Kolkata, the capital of West Bengal, and Hyderabad, the capital of Telangana, are known for their rich history, diverse population, and modern infrastructure.
3. "Aurora kinase is responsible for antioxidant action." This statement is false. Aurora kinase is a family of serine/threonine kinases that play a crucial role in cell division and mitosis. They are involved in the regulation of the cell cycle and the formation of the mitotic spindle. Antioxidant action, on the other hand, is typically associated with enzymes and molecules that protect cells from oxidative damage caused by free radicals. Examples of such antioxidants include superoxide dismutase, catalase, and glutathione peroxidase.
Given the analysis of each statement, the correct answer is Option A, which states that only the first two statements are true. The Salarjung Museum in Hyderabad is indeed famous for its priceless artifacts, and both Kolkata and Hyderabad are recognized as metropolitan cities. However, Aurora kinase is not responsible for antioxidant action, making the third statement false.
Understanding the cultural significance of landmarks and the biological functions of specific enzymes is essential for answering such questions accurately. It is important to distinguish between the roles of different enzymes and the characteristics of cultural and urban landmarks to avoid common misconceptions.
