Read the following Assertion and Reason and choose the correct option. Assertion: Residual volume can be used in clinical diagnosis Reason: Residual volume in a healthy man averages from 1100 mL to 1200 mL.

Options

  1. ABoth Assertion and Reason are true and Reason is correct explanation of Assertion
  2. BBoth Assertion and Reason are true but Reason is not the correct explanation of Assertion
  3. CAssertion is true but the Reason is false
