Which of the following items should be insured under the proposed program for National Auto Parts Ltd.?

Insuring all structures and certain business interruptions is essential in a construction project like that of National Auto Parts Ltd., as it encompasses both tangible assets and potential financial losses.

The inclusion of all structures ensures that not just the main building, but also additional components like temporary structures, are protected from risks such as accidents, damage, or theft during the construction phase. This approach mitigates the financial impact of unexpected events that could disrupt the project.

Additionally, accounting for certain business interruptions is crucial because delays or unforeseen events may lead to loss of income or additional expenses. By including this coverage, the program ensures continuity of operations and provides financial protection, allowing the business to recover from setbacks more effectively.

The focus on comprehensive insurance coverage in this scenario reflects a proactive approach to risk management in construction projects, which is vital for safeguarding investments and ensuring the project's success.
