The correct answer is: A. Extra benefits are allowed by the insurer in a life policy on payment of an extra premium.
Option B is incorrect because double accident benefit is not a free item in a life policy. It is an additional benefit that can be purchased for an extra premium.
Option C is incorrect because permanent disability, like DAB, is not a free benefit and not chargeable. It is an additional benefit that can be purchased for an extra premium.
Option D is incorrect because extra premium for health and extra premium for extra benefits are not identical. Extra premium for health is usually higher than extra premium for extra benefits.
Extra benefits are additional benefits that can be added to a life policy for an extra premium. These benefits can include things like accidental death benefit, waiver of premium, and terminal illness benefit. Extra benefits can provide you with additional peace of mind and financial protection in the event of a life event.
When choosing extra benefits, it is important to consider your individual needs and circumstances. You should also make sure that you understand the terms and conditions of the extra benefits before you purchase them.
