Final answer:
The additional coverage that is in the Broad Form but not the Basic Form is 'collapse'. Both forms usually cover fire, explosion, and smoke, but collapse is specific to the Broad Form. So, the correct answer is option c.
Step-by-step explanation:
The broad form type of insurance coverage includes additional protections that are not found in the basic form. Specifically, collapse is included in the broad form but not in the basic form. The broad form typically covers a broader spectrum of risks and is likely to cover more kinds of damage, while the basic form provides a more limited coverage.
Coverage options like fire, explosion, and smoke are typically included in both basic and broad forms. However, it's collapse that distinguishes the broad form from the basic form, offering extra protection in case a building or any part of the property collapses due to specific causes outlined in the policy.
So, the correct answer is option c.
