Answer:
D. Variation
Explanation:
The word "converse" is a variation of the word "conversation"
When a word is said to be a variation of another word, it means that it was derived from the word and is used in a different form.
To converse is to have a talk with someone
To have a conversation means the same thing.
The only difference is that "converse" is a verb and "conversation" is a noun.
