The correct answer is: B. average load.
The diversity factor is the ratio of the sum of the individual loads to the total load. It is used to determine the average load on a system. The average load is important because it is used to size the system components, such as the generator, transformers, and conductors.
The peak load is the maximum load that a system must be able to carry. It is important because it is used to size the system components for short-term overloads.
The kWh generated is the total amount of energy that a system produces over a period of time. It is important because it is used to determine the cost of operating the system.
E is not the correct answer because the diversity factor does not help in determining kWh generated.
