Final answer:
The rider that G purchased is called the Return of Premium Rider and it provides a refund of all the premiums paid if G outlives his policy.
Step-by-step explanation:
The name of the rider that G purchased is the Return of Premium Rider. This rider is an additional feature that can be added to a level term life insurance policy. It provides a refund of all the premiums paid if the policyholder outlives the term of the policy.
For example, let's say G purchased a 20-year level term policy and opted for the Return of Premium Rider. If G remains alive at the end of the 20-year term, the insurance company would return all the premiums paid over those 20 years.
It's important to note that the Return of Premium Rider typically increases the cost of the insurance policy since it offers the potential for the policyholder to receive a refund.
