Final answer:
The correct pronoun is 'nos' which means 'us' in English.
Step-by-step explanation:
The pronoun that corresponds to the subject 'Nosotros' in the sentence 'Nosotros queremos dar un regalo a ellos' is A. me. This answer choice is incorrect because 'me' is the pronoun for the first person singular form in Spanish, while 'Nosotros' is the first person plural form. The correct pronoun is the reflexive pronoun 'nos', which means 'us' in English.
