Best answer
The correct answer is (a) Scavenging ratio

The explanation: The various factors necessary to select a ring for an engine are dimensions of the engine block, piston design, piston displacement, piston speed, bore to stroke ratio, cooling capacity, crankcase pressure whereas scavenging ratio has no main role in piston ring selection.
