Answer:
Language with positive connotation or technical language im not sure
Explanation:
I also agree that the answer is B: whom
in this sentence you are using the preposition + whom grammar structure. Whom is considered an object pronoun and is used when asking who will receive the action, which in this case, I believe is, baking those cookies. Hopefully this makes sense and good luck.
The inside address is usually the address of the recipient, the person the letter is being sent to. The sender's address is at the top, then the date, followed by the recipient's address.
ANSWER: (A) who the letter is being sent to.
Hope this helps! :)
