Assertion (A): A wasted spark system fires two cylinders simultaneously.
Reason (R): The two paired cylinders reach top dead centre together.
Select the correct answer from the options below.
Answer: B
One is on compression and fires the mixture while the other is on exhaust and sparks harmlessly into spent gas. The pairing is exactly what allows one coil to serve two cylinders, so the reason explains the arrangement. Naming the cost of a choice alongside its benefit is what turns a fact into a design decision. Tracing the requirement back to the physical constraint that produces it makes the answer follow. A symptom that appears under one condition and not another is what narrows the diagnosis quickly.
