The following sentence has been divided into parts. One of them may contain an error. Select the part that contains the error from the given options. If you don’t find any error, mark ‘No error’ as your answer.

Ramya is working / hardly / to get good marks.

The correct option containing the error is hardly.

Explanation:
In the given sentence, "Ramya is working / hardly / to get good marks", the word "hardly" is used incorrectly.
"Hardly" is an adverb that means "scarcely" or "barely" (almost not at all). Using "hardly" in this context changes the intended meaning to suggest that Ramya is doing almost no work.

The intended meaning is that Ramya is putting in a lot of effort to get good marks. The correct word to describe working with great effort or diligence is the adverb "hard".

Correct Sentence:
Ramya is working hard to get good marks.

Therefore, the part containing the grammatical error is "hardly".
