Explanation: To understand the context of the statements provided, it is essential to delve into the geography, economy, and administrative details of Kerala, a state in southern India.
**Kerala's Tea Production:**
Kerala is known for its tea production, but it is not the largest tea manufacturer in India. The state of Assam holds the title of being the largest tea-producing state in India. Assam's tea industry is renowned for its high-quality tea, particularly the Assam tea, which is one of the most popular varieties in the world. Kerala, while it does produce tea, especially in regions like Munnar, is not the leading producer in the country.
**Backwaters of Kerala:**
The backwaters of Kerala are a network of canals, rivers, and lakes that are interconnected and form a unique inland water system. These backwaters are a significant part of Kerala's geography and are a major tourist attraction. They are not coastal waters but are considered inland waters because they are located inland and are not directly connected to the sea. The backwaters are an important part of Kerala's ecosystem and are used for transportation, fishing, and tourism.
**Capital of Kerala:**
Thiruvananthapuram, also known as Trivandrum, is the capital city of Kerala. It is located in the southern part of the state and is known for its cultural and educational institutions. The city is a major center for government administration and is home to the Kerala State Assembly and other important government offices.
In summary, the correct statements are that the backwaters of Kerala are an example of inland waters and that Thiruvananthapuram is the capital of Kerala. The statement about Kerala being the biggest tea manufacturer in India is incorrect. Therefore, the correct answer is option D, which includes only the true statements.
