The correct answer is: C. Seeta asked me if I could give her my pen.
Seeta is using the modal verb “could” to ask for a favor. This means that she is not demanding that I give her my pen, but is instead asking me if I would be willing to do so. The use of “could” also makes it clear that Seeta is not expecting me to give her my pen without hesitation. She is aware that it is a request, and is willing to accept a “no” answer.
Option A is incorrect because it uses the indicative mood, which is used to make statements about reality. In this case, Seeta is not making a statement about reality, but is instead asking a question.
Option B is incorrect because it uses the wrong form of the verb “can.” The correct form to use in this case is “could.”
Option D is incorrect because it uses the informal pronoun “i.” The formal pronoun “I” should be used in this case.
