Question:
<p><strong>Assertion (A):</strong> H.C.F. of smallest prime and smallest composite is 2.<br />
<strong>Reason (R):</strong> Smallest prime is 2 and smallest composite is 4 so their H.C.F. is 2.</p>
<p style="display:inline">Both A and R are true and R is the correct explanation of A.</p>
<p style="display:inline">Both A and R are true but R is not the correct explanation of A.</p>
<p style="display:inline">A is true but R is false.</p>
<p style="display:inline">A is false but R is true.</p>
