The correct answer is C. She requested me to bring her a glass of water.
In this sentence, the speaker is using the verb “request” to ask the listener to do something. The listener is the direct object of the verb, and the action that is being requested is “bring me a glass of water.” The word “please” is a polite way of making a request, and it indicates that the speaker is hoping that the listener will comply with their request.
Option A is incorrect because it uses the infinitive form of the verb “to bring.” The infinitive form is used to express a general idea or purpose, and it is not typically used to make requests.
Option B is incorrect because it uses the past tense form of the verb “to bring.” The past tense form is used to describe actions that have already happened, and it is not typically used to make requests.
Option D is incorrect because it uses the subjunctive mood. The subjunctive mood is used to express wishes, possibilities, and conditions that are not real or certain. It is not typically used to make requests.
