A silicon speciman is made into a P-type semi-conductor by dopping, on an average, one Indium atom per \[5\times {{10}^{7}}\]silicon atoms. If the number density of atoms in the silicon specimen is \[5\times {{10}^{28}}\text{atoms}/{{m}^{3}}\] then the number of acceptor atoms in silicon per cubic centimetre will be [MP PMT 1993, 2003]

• A.            \[2.5\times {{10}^{30}}atoms/c{{m}^{3}}\]                
• B.            \[1.0\times {{10}^{13}}atoms/c{{m}^{3}}\]
• C.            \[1.0\times {{10}^{15}}atoms/c{{m}^{3}}\]                
• D.            \[2.5\times {{10}^{36}}atoms/c{{m}^{3}}\]
