I will mark brainliest

the correct answer is: (A) The title/summary of what you need.

Explanation:

The subject is what the receiver see's when going across the email. Putting the summary of what the email is about in subject allows them to see what the email is mainly about seeing if they should continue reading the email or not. So providing the summary pf the email lets the receiver know what the email is about. Hope this helps! :D
