The following sentence has been split into four segments. Identify the segment that contains a grammatical error.
She has given / me a book / last week / which I returned.

Correct option is A

Option (a) contains a grammatical error.
Explanation:
The use of present perfect tense ("has given") is incorrect with definite past time expressions like “last week”. When referring to a specific point in the past, we must use the simple past tense.
Correct sentence: She gave me a book last week, which I returned.
Grammatical Rule Used:
· Present perfect (has/have + V3) is not used with past time expressions like yesterday, last week, in 2020, etc.
· Use past simple (V2) with specific time indicators.
Example:
· Incorrect: I have met him yesterday.
· Correct: I met him yesterday.
Information Booster:
Words like ever, just, already, recently, never, yet go with present perfect, but last week, last month, ago, in 1995 go with past simple.
