Best answer
The correct choice is (a) Machining the narrow grooves

For explanation: The advantages of having a reduced ring width are better resistance to scuffing, better resistance to ring flutter, problems on ring inertia are reduced, lower piston height, and consequently lower engine height and the disadvantage is machining the narrow grooves I’m the piston accurately is quite difficult.
