10. What is the correct definition of a guarantee versus an indemnity?

A. A guarantee involves only insurance coverage, whereas an indemnity involves a loan agreement.

Answer: (D)

Explanation

A guarantee is a secondary obligation where one promises to pay if the primary debtor defaults, while an indemnity is a primary obligation to compensate for loss regardless of default, which aligns with the definitions in the context.
