Best answer
The correct choice is (b) 2

The best explanation: The crankshaft are generally of two types, they are one piece and built up. In the built-up construction the crankpins and journals are bolted to crank arms, which also serves as flywheels. One-piece construction is almost universally used for automotive crankshaft.
