Assertion : Use of ball bearings between two moving parts of a machine is a common practice. Reason : Ball bearings reduce vibrations and provide good stability.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of the assertion
  2. BIf both assertion and reason are true but reason is not the correct explanation of the assertion
  3. CIf assertion is true, but reason is false
  4. DBoth assertion and reason are false statements.

Correct answer

C. If assertion is true, but reason is false

Step-by-step solution

Assertion is correct. But ball bearing is used for reducing friction.
