Best answer
The correct option is (a) the amount of power which is being absorbed by propeller

To elaborate: How much power is being absorbed by propeller can be measured by using activity factor. Activity factor varies from 90-200. A typical large turboprop will have an activity factor of 140. Lighter aircraft can have activity factor as 100 typically.
