Whichever means any one from a specific or limited group of choices. It is used when the available options are already known or understood.
For example:
- Take whichever seat is available.
- Pick whichever color you prefer.

Definition of Whatever
Whatever means anything at all or no matter what. It refers to an unlimited range of possibilities rather than a fixed set.
For example:
- Eat whatever you like.

- Believe whatever you want.
The speaker does not limit the available options.

Sometimes yes, but not always.
Correct:
