\(M_n~\text{and}~M_p\) represent the mass of the neutron and proton respectively. An element having mass \(M\) has \(N\) neutrons and \(Z\)-protons, then the correct relation will be:
1. \(M <\left \{N.M_n+Z.M_p \right \}\)
2. \(M >\left \{N.M_n+Z.M_p \right \}\)
3. \(M =\left \{N.M_n+Z.M_p \right \}\)
4. \(M =N\left \{M_n+M_p \right \}\)
1. \(M <\left \{N.M_n+Z.M_p \right \}\)
2. \(M >\left \{N.M_n+Z.M_p \right \}\)
3. \(M =\left \{N.M_n+Z.M_p \right \}\)
4. \(M =N\left \{M_n+M_p \right \}\)
