The correct answer is:

(c) Willan’s line method

The Willan's line method is also known as the fuel rate extrapolation method. It is used to determine the brake-specific fuel consumption (BSFC) by extrapolating the fuel consumption data to zero brake power, allowing for the estimation of engine fuel efficiency at different power outputs.
