Final answer:
The formal, affirmative command form of the verb 'traer' is 'tráigame' and it is used to ask someone to bring something for you.
Step-by-step explanation:
The correct answer is B. tráigame.
The sentence is asking someone to bring the green plaid shirt, so we use the formal, affirmative command form of the verb traer (to bring). The pronoun 'me' is used to indicate that the action is being done for the speaker. The command form for 'usted' (you formal) is 'tráigame'.
For example, if you want to ask a waiter to bring you a glass of water, you would say 'Tráigame un vaso de agua, por favor' (Bring me a glass of water, please).
