Final answer:
Increased Cost of Construction is not one of the five standard extensions of coverage under a building and personal property coverage form in commercial insurance policies; it is a separate additional coverage.
Step-by-step explanation:
The question is about identifying which option is not one of the five extensions of coverage available under the building and personal property coverage form used in commercial insurance policies. After reviewing typical coverage forms, we can conclude that the answer is D. Increased Cost of Construction.
This is not typically one of the five extensions of coverage. Instead, it is a separate coverage that can be added to a policy to cover the additional costs to comply with building codes after a covered loss.
The other options listed (A, B, C, and E) are standard extensions under the building and personal property coverage form. They extend protection to areas such as newly acquired property, personal effects, valuable papers, and some outdoor property, subject to certain conditions and limitations.
