What is(are) some of the function(s) of the engine's crankshaft? A. To drive the oil pump B. To change verticle motion into rotary motion. C. To distribute energy from the D. To operate the valves.

# 1<br />The crankshaft is a vital component in an engine. It is responsible for converting the linear motion of the pistons into rotational motion. This is done by changing the vertical motion of the pistons into rotary motion.<br /><br />## Step 2<br />The crankshaft does not drive the oil pump. The oil pump is typically driven by a belt connected to the crankshaft, but the crankshaft itself does not drive the oil pump.<br /><br />## Step 3<br />The crankshaft does not operate the valves. The valves are typically operated by camshafts, which are connected to the crankshaft via a timing chain or belt.<br /><br />## Step 4<br />The crankshaft does not distribute energy from the engine. The energy distribution is typically done by the engine's internal components, such as the pistons and cylinders.<br /><br /># Answer: <br />B
