Assertion : $\mathrm{HCl}$ converts pepsinogen into active enzyme pepsin. Reason: Pepsin converts protein into proteoses and peptones.

  • A
    If both assertion and reason are true and reason is the correct explanation of assertion.
  • Correct answer
    B
    If both assertion and reason are true but reason is not the correct explanation of assertion.
