You understand what I am saying. Add question tag:
ADo you
BDon't you
CDoesn't you
DDidn't you
Answer:
B. Don't you
Read Explanation:
If the main verb is positive, the question tag is usually negative, and vice versa. If there is no auxiliary verb, "do" is often used.

Question Tag: "You understand what I am saying, don't you?"
In this sentence, "understand" is a positive verb, so the question tag "don't you" is negative.
