Explanations:The question involves evaluating the accuracy of three statements related to historical landmarks and geographical facts about Indian cities. Let's break down each statement:
1. "Gateway of India was built by George Willet to honour the visit of King George V and Queen Mary to Mumbai." This statement is true. The Gateway of India was constructed in the early 20th century to commemorate the visit of King George V and Queen Mary to Mumbai in 1911. The construction was commissioned by the British government to welcome the royal couple, and it was designed by the architect George Wittet (not George Willet, as the question states).
2. "Mumbai is the capital city of India." This statement is false. Mumbai is a major city and the capital of the state of Maharashtra, but it is not the capital city of India. The capital city of India is New Delhi. This is a common misconception, as Mumbai is often mistaken for the capital due to its prominence as a financial and cultural hub.
3. "Howrah Bridge is in Kolkata." This statement is true. The Howrah Bridge, also known as Rabindra Setu, is a famous landmark in Kolkata, West Bengal. It is a suspension bridge that spans the Hooghly River and connects the city of Howrah with Kolkata. The bridge is an iconic symbol of Kolkata and is one of the busiest bridges in the world in terms of pedestrian and vehicular traffic.
Given these evaluations, the correct answer is Option D, which states that only the first and third statements are true. The second statement is false, as Mumbai is not the capital city of India. Understanding the historical context and geographical facts about these landmarks and cities is crucial for correctly identifying the true statements.
