Answer:
A. 0%
Step-by-step explanation:
Premiums are tax-deductible according to the payroll system. Therefore, the answer should be "0%".
As the premiums are tax-deductible, so the employee does not need to pay any taxes. Therefore, Gary does not pay any tax from his claim on that premium. Hence, whatever he contributes during his tenure, Gary does not need to pay any tax on that.
