If an oil filter element becomes completely clogged, what happens?

Oil flow to the engine will be restricted.
Oil will be bypassed back to the oil tank.
Bypass valve will open, and the oil pump will supply unfiltered oil.
The engine will automatically shut down.

The correct answer is: Bypass valve will open, and the oil pump will supply unfiltered oil.

Possible explanation When an oil filter element becomes completely clogged, the oil will not be able to pass through it for filtering. As a result, the bypass valve in the oil filter will open to allow unfiltered oil to flow back to the oil tank. This is a temporary measure to ensure that oil is still reaching the engine and not completely cut off, but it means that unfiltered oil is being supplied to the engine. This can be harmful as the unfiltered oil may contain dirt and debris that could damage the engine. Option A is incorrect because the oil flow is not restricted, it is just bypassed. Option B is partially correct as the unfiltered oil does go back to the oil tank, but it does not shut off completely. Option D is incorrect as the engine will not automatically shut down in this situation.
