Respuesta :
id say D. it is the closest to an antonym. ruthless and merciful have opposing meanings and so passive and aggressive
Answer:
Passive
Explanation:
Ruthless is the opposite of merciful, so you are looking for the opposite of aggressive:
When you are aggressive you do things back to another person or thing. The opposite of that would be passive, meaning that you let things happen to you in a way, or that you don't fight back.
Hope this makes sense!
