Final answer:
Rebating is when an insurance agent offers to split their commission with a client, which is typically considered an unfair trade practice and is illegal in many jurisdictions.
Step-by-step explanation:
If an insurance agent offers to split their commission with a prospective applicant, this would be considered d. Rebating. Rebating in the insurance industry is the act of returning a portion of the premium or the agent's commission to the insured or offering some sort of financial incentive as an inducement to purchase the policy. While rebating laws vary by state, it is generally not allowed and can be seen as an unfair trade practice because it creates an unequal marketplace and could influence the purchase decision of prospective clients.
