Explanations:The phrase "is known as" is commonly used in English to introduce a nickname or a well-known title for a person, place, or thing. In the context of the question, "God's Own Country" is a nickname or title given to the state of Kerala in India, emphasizing its natural beauty and unique characteristics. The correct grammatical structure to use in this context is "is known as," which includes the auxiliary verb "is" to form the present tense.
Let's break down the usage of the phrase "is known as" in more detail. The phrase "is known as" is used to describe a situation where a person, place, or thing is widely recognized by a particular name or title. For example, "Paris is known as the City of Light" or "Albert Einstein is known as the father of modern physics." In each of these examples, the phrase "is known as" is used to introduce a well-known title or nickname.
It is important to note that the phrase "is known as" is different from "known for." The phrase "known for" is used to describe qualities, achievements, or characteristics that a person, place, or thing is recognized for. For example, "Kerala is known for its backwaters and beaches." In this case, "known for" is used to describe the qualities that make Kerala famous, rather than a nickname or title.
Another common mistake is the incorrect usage of "knows for" instead of "is known as." The phrase "knows for" is not grammatically correct in this context. The correct phrase to use is "is known as," which includes the auxiliary verb "is" to form the present tense.
In summary, the correct answer to the question is "Is known as" because it is the proper phrase to introduce a nickname or title, and it correctly uses the auxiliary verb "is" to form the present tense. This usage is essential for maintaining grammatical correctness and clarity in the sentence.
