Induction manifold is:

• A. Pipes that lead exhaust gases away to main outlet
• B. Pipes and ducts which lead the fuel-air mixture from the carburetor to the individual cylinder
• C. A tube that feeds fuel directly into the combustion chamber
• D. The intake manifold is silent

Answer: (B)

The induction manifold is the network of pipes and ducts that carries the air-fuel mixture from the carburetor to each cylinder. Its primary job is to deliver that mixture evenly to every cylinder so the engine can breathe properly and run smoothly. That’s why it’s described as the system that distributes the intake charge via runners to the individual cylinders.

Exhaust pipes handle exhaust gases, not the incoming mixture, so that option isn’t describing the induction path. Fuel delivered directly into the combustion chamber represents a direct-injection setup, which bypasses the intake manifold’s distribution role. Saying the intake manifold is silent isn’t a functional description and doesn’t define what the part does.
