The correct answer is C. Sitara asked me whether I had taken my laptop.
The sentence “Have you taken your laptop?” is a question in the present perfect tense. It is used to ask about something that has happened or been done recently. In this case, Sitara is asking the speaker if they have taken their laptop.
The answer “A. Sitara asked me in had taken the laptop” is incorrect because the past perfect tense is used to talk about something that happened before another event in the past. In this case, there is no other event in the past that Sitara is referring to.
The answer “B. Sitara asked me if we had taken the laptop” is incorrect because the plural pronoun “we” is used to refer to more than one person. In this case, Sitara is only asking the speaker about their own actions.
The answer “D. Sitara asked me if suppose I have taken my laptop” is incorrect because the word “suppose” is used to express a possibility or a suggestion. In this case, Sitara is not expressing a possibility or a suggestion, they are asking a direct question.
