Explanation:
<em>atomic</em><em> </em><em>number</em><em> </em><em>=</em><em> </em><em>no.</em><em> </em><em>of </em><em>protons</em><em> </em><em>=</em><em> </em><em>1</em><em>3</em>
<em>therefore</em><em> </em><em>atomic </em><em>number</em><em> </em><em>of </em><em>aluminium</em><em> </em><em>is </em><em>1</em><em>3</em><em> </em><em>as </em><em>given</em>
<em>so </em><em>option</em><em> </em><em>D </em><em>1</em><em>3</em><em> </em><em>is </em><em>correct</em><em> </em><em>option</em><em> </em><em>.</em>
