Final answer:
The provision that pays a benefit if 'P' is blinded is the accidental death and dismemberment provision, as it covers losses due to accidents, unlike other provisions such as the waiver of premium, accelerated death benefit provisions, or guaranteed insurability rider.
Step-by-step explanation:
In the scenario where 'P' is blinded in an accident, the provision of his life insurance policy that will pay a stated benefit amount is the accidental death and dismemberment provision. This provision specifically provides benefits for the insured if they suffer a loss such as blindness due directly to an accident. It is important to differentiate this from other provisions like the waiver of premium provision, which waives the policy premiums if the insured becomes disabled, the accelerated death benefit provision, which allows the insured to receive a portion of their death benefit early if they are diagnosed with a terminal illness, and the guaranteed insurability rider, which allows the insured to buy additional insurance coverage without proving insurability.
