Question

What word most contributes to the formal tone of the email?

A. Professor
B. please
C. attached
D. resolve

Answer 1

Resolve

Step-by-step explanation:

The word professor is the reason why the email is formal but not what makes it. Please is common courtesy to which all people should. Attached is just a guiding word from the professor reading the email. Resolve is another way to say solve or fix but both of those are more slang-like and or common, to say the least.
