Final answer:
The loss that would be covered by the causes of loss - broad form, but NOT by the causes of loss - basic form is Earthquake loss of livestock. The correct option is A.
Step-by-step explanation:
The causes of loss - broad form coverage in livestock insurance typically provides coverage for a wider range of perils compared to the causes of loss - basic form coverage.
Based on the options provided, the loss that would be covered by the causes of loss - broad form, but NOT by the causes of loss - basic form is Earthquake loss of livestock (option A).
This means that if a student has insurance coverage with the causes of loss - broad form, they would be protected against losses in the event of an earthquake impacting their livestock.
However, the causes of loss - basic form coverage would not provide the same coverage for earthquake-related losses. The correct option is A.
