Answer:
d. a counterclaim
Explanation:
A counterclaim is not included in a complaint. This is because a complaint is a description of your problem and all the procedures you have followed in order to resolve it before reaching the point where you no longer know how to proceed.
This shows that a complaint is an expression of not being satisfied about a thing, hence it involves an individual reporting an issue to the appropriate authorities.
A counterclaim involves refutting or denying the issues raised by a complainer. This is not part of a complaint because complaint is not a dialogue or discussion that goes back and forth. It only involves stating your grievances.
