\[{{M}_{n}}\] and \[{{M}_{p}}\] represent mass of neutron and proton respectively. If an element having atomic mass M has N-neutron and Z-proton, then the correct relation will be [CBSE PMT 2001]

• A.            \[M<[N{{M}_{n}}+Z{{M}_{P}}]\]                                    
• B.            \[M>[N{{M}_{n}}+Z{{M}_{P}}]\]
• C.            \[M=[N{{M}_{n}}+Z{{M}_{P}}]\]                                    
• D.            \[M=N[{{M}_{n}}+{{M}_{P}}]\]
