Final answer:
Out of the listed items, only prescription sunglasses, if they correct vision, can be considered deductible medical expenses on Schedule A. Over-the-counter vitamins, aesthetic cosmetic surgery, and gym memberships for general health are typically not deductible.
Step-by-step explanation:
The deductible medical expenses on Schedule A are those that are considered necessary and primarily for the prevention or alleviation of a physical or mental defect or illness. Based on the options provided:
- Over-the-counter vitamins and supplements are generally not deductible unless they are recommended by a medical practitioner as treatment for a specific medical condition.
- Cosmetic surgery for purely aesthetic purposes is not deductible, as it is not medically necessary.
- A gym membership for general health and fitness is not deductible, as it is for the maintenance of general health and not for a specific medical condition.
- Non-prescription sunglasses for sun protection are not deductible; however, prescription sunglasses, which correct vision, may indeed be considered a deductible medical expense.
The best selection for a deductible medical expense on Schedule A among the given choices would be prescription sunglasses, provided they are for vision correction.
