Final answer:
Greg has Specific coverage, meaning each of his buildings is insured under a separate policy customized for its value and risks.
Step-by-step explanation:
If Greg owns several buildings, each at a different location, and each is insured on a separate policy, the type of coverage Greg has is Specific coverage. Specific insurance policies are individual policies that cover specific assets at specific locations, with a set amount of insurance for each asset. This means that each of Greg's buildings will have its own individual policy tailored to the value and risks of that specific property.
