Answer: a. Only one policy will pay, the premiums for the other contracts will be returned.
Step-by-step explanation:
When there are multiple insurance contracts from the same insurer and these contracts have a ''Other Insurance With This Insurer'' provision, it means that in cases where the insured wants to claim, they can choose whichever of the policies they want and that one will pay out but they cannot pick them all.
The premiums paid on the other contracts/s will be returned to the insured because it represents excess coverage.
