Read the sentence to find out whether there is any grammatical or idiomatic error in it. The error, if any, will be in one part of the sentence. The corresponding letter of that part is the answer. If the given sentence is correct as it is, then choose option ‘No error’ as the answer response. (Ignore errors of punctuation, if any).

When the author writes (A)/ his stories, he tries to include (B)/ a mortal lesson that will (C)/ resonate with his readers (D)/ no error (E).

Correct option is A

The error lies in part (C) of the sentence.
This phrase is incorrect because " mortal" means relating to death or causing death, which doesn't make sense in the context of the sentence. The correct word should be "moral," which refers to a lesson or principle about right and wrong.
Thus, “mortal” should be replaced with “ moral”.

Correct Answer: (C)

Summary of each part:

(A) When the author writes → correct present tense usage
(B) his stories, he tries to include → correct structure
(C) a mortal lesson that will → incorrect; “mortal” should be “moral”
(D) resonate with his readers → correct phrase

Conclusion:

Error is in (C) due to wrong word usage (“mortal” instead of “moral”).
