You have the below requirements for building a web application:
Requirement A-Provide the ability to authenticate the user;
Requirement B-Provide the ability to post to forums;
You note that for the user to post to forums, he has to first login and be
authenticated.
The relation between Requirement A and Requirement B is:
a. Cover
b. Subset
c. Effort
d. Necessity

from the available options "Necessity" is the correct option.

Necessity: A requirement and another related requirement must be implemented at the same time for a specific reason.

From the Business Analysis practice Guide, it is kind of implementation dependency. Without implementing login, user cannot post in forum.

For your ready reference, here are the details: (Definition is taken fromm BABOK,which is not reference for PMI-PBA)

Necessity: A requirement and another related requirement must be implemented at the same time for a specific reason.
Effort: A requirement is easier to implement if a related requirement is implemented at the same time.
Subset: A requirement is a decomposed outcome (one of the children) of another requirement.
Cover: A higher-level requirement is the sum of its sub-requirements. In this case, all of the sub-requirements must be implemented in order for this higher-level requirement to be met.
Value: Including a particular requirement increases or decreases the desirability of implementing a related requirement.
