Identify the part of the following sentence in which there is an error.
Ram told / me that / he has / lost his book.

Correct option is C

Option (c) contains an error.
Detailed Explanation:
· The reporting verb “told” is in the past tense.
· Therefore, the verb in the reported clause should also shift to past perfect tense.
· The phrase “he has lost” (present perfect) is incorrect here.
· Correct form should be: “he had lost his book.”
Grammatical rule used:
Backshift of tense in indirect speech
· Present Perfect → Past Perfect when the reporting verb is in past tense.
Correct sentence:
Ram told me that he had lost his book.
Example:
· Direct: He says, “I have finished my work.”
· Indirect: He said that he had finished his work.
Information Booster:
· Tense backshift is not applied if the statement is a universal truth.
