Final answer:
The correct option to complete the sentence is 'Dátelo', which means 'Give it to yourself' in Spanish.
Step-by-step explanation:
The correct option that completes the sentence is C. Dátelo.
The sentence, Necesito un vaso de agua ahora, translates to 'I need a glass of water now' in English. The verb 'dar' means 'to give' in Spanish, and when conjugated in the second-person singular form, it becomes 'darte'. The pronoun 'te' indicates that the action is being done to you, and 'lo' represents the direct object, which in this case is 'a glass of water.'
Therefore, Dátelo is the correct option to complete the sentence, meaning 'Give it to yourself.'
