An insured with a major medical policy has a per cause deductible of $100.

Aper cause deductiblemeans the insured pays a $100 deductible for each separate medical condition or cause of treatment. The insured visits the doctor three times for injuries, each costing $200. Assuming each visit is for adifferent injury(to calculate the minimum amount, we consider the maximum number of deductibles), the insured pays a $100 deductible per visit (3 visits × $100 = $300). If the policy includes coinsurance (not specified but common in major medical policies), additional costs may apply, but the question asks for theminimum amount, which is the total deductibles for three separate causes.

Calculation:

Visit 1: $100 deductible (first injury).

Visit 2: $100 deductible (second injury).

Visit 3: $100 deductible (third injury).

Total: $100 × 3 = $300.

If all visits were for the same injury, only one $100 deductible would apply, but the question implies separate causes to reach the minimum of $300.

Option A: Incorrect. $100 assumes one deductible for a single cause, not three visits.

Option B: Incorrect. $200 does not account for three separate deductibles.

Option C: Correct. $300 reflects a $100 deductible for each of three separate injuries.

Option D: Incorrect. $500 exceeds the minimum, possibly including coinsurance not specified.
