D is the correct answer as four-stroke diesel engine size is massive compared to 2 strokes. Also, remember more the mass more will be inertia. So, to balance the inertia, we need bigger mass flywheel.

Option D is the right answer because 4 stroke requires heavy flywheel than 2 strokes more than the no of rpm lighter flywheel it requires.

A is correct because in four-stroke engine for every power stroke 2 revolution of the crank which creates more vibration these vibration and fluctuations are absorbed by the bigger flywheel.

The flywheel in a four stroke petrol engine is heavier than in a two stroke petrol engine and there is no flywheel in a diesel engine.

Option a -is for petrol.
Option b - is for diesel.
Option b - is for diesel.

Right answer should be D.
As speed decreases, the torque produced increases.
Thus, larger flywheel requires.
As speed decreases, the torque produced increases.
Thus, larger flywheel requires.

Right answer should be option D because of Torque will be more at low speed and there will be a power stock in two round of crank shaft in diesel engine while there will be a power stock in one round of crank shaft in petrol engine.

Why not option D ?
As increasing speed time between two successive spark production is less.
So for less speed high flywheel is required.
