A person has insurable interest in the life of which of the following?

Insurable interest refers to the requirement that an individual taking out a life insurance policy must have a legitimate interest in the continued life of the insured. This can take various forms, and all the scenarios provided encompass valid instances of insurable interest.

Having insurable interest in a child or grandchild stems from the emotional bond as well as financial dependence one may have on them. Parents and grandparents typically bear responsibilities that include the wellbeing and future of their dependents, which justifies their insurable interest in these family members.

Furthermore, individuals have insurable interest in anyone upon whom they are wholly or partly dependent. This includes situations where one person relies financially on another, creating a legitimate concern about the financial implications of that person's death.

Lastly, having a pecuniary interest in a person means the individual stands to gain or avoid loss financially from that person's continued life. Insurable interest in business contexts may often involve partners, key employees, or others upon whose life the financial stability or success of a business depends.

Since all the options reflect scenarios where insurable interest exists, it is accurate to assert that the individual has insurable interest in all these relationships.
