Let \[{{m}_{p}}\]be the mass of a proton, \[{{m}_{n}}\]the mass of a neutron, \[{{M}_{1}}\]the mass of a \[_{10}^{20}Ne\] nucleus and \[{{M}_{2}}\]the mass of a \[_{20}^{40}Ca\]nucleus. Then [IIT 1998; DPMT 2000]

• A.            \[{{M}_{2}}=2{{M}_{1}}\]       
• B.            \[{{M}_{2}}>2{{M}_{1}}\]
• C.            \[{{M}_{2}}<2{{M}_{1}}\]       
• D.            \[{{M}_{1}}<10({{m}_{n}}+{{m}_{p}})\]
