Explanation: The phrase "God's Own Country" is a well-known slogan used to describe the state of Kerala in India. This slogan highlights the natural beauty and scenic landscapes of the state, which include lush greenery, serene backwaters, and pristine beaches. The phrase is used in marketing and tourism campaigns to attract visitors to Kerala.
In English grammar, the phrase "is known as" is used to indicate a nickname or a well-known title. For example, "Kerala is known as God's Own Country." This construction includes the verb "is" and the phrase "known as," which together form a complete and grammatically correct sentence.
The other options provided in the question are incorrect for the following reasons:
- "Known for" is used to describe what something is famous for, not what it is called. For example, "Kerala is known for its backwaters."
- "Known as" is missing the verb "is," making it grammatically incomplete.
- "Knows for" is not a correct English phrase and does not fit the context of the question.
Understanding the correct usage of these phrases is important for both grammatical correctness and clarity in communication. In the context of state branding and tourism, using the correct phrase ensures that the intended message is conveyed accurately and effectively. Therefore, the correct answer is "Is known as," as it correctly conveys that Kerala is referred to by the nickname "God's Own Country."
