the antonym of "employ"

[any77]

Hello,

What is the antonym of the word "employ" and why? Thanks.

The selections are listed below:
a) leave idle b) deny access

While the interpretation of "employ" in Merriam-Webster is:
to make use of (someone or something inactive) *employ a pen for sketching* b : to use (as time) advantageously *a job that employed her skills* c (1) : to use or engage the services of (2) : to provide with a job that pays wages or a salary *a company that employs fifty*

Well, I am confused.
In my mind, if the word "employ" means "in use", while the antonym is idle; However, if it means "do use", I think deny access is better.
