Question

In which of the following options the order of arrangement does not agree with the variation of property indicated against it?, A l 3 + M g 2 + N a + F - (increasing ionic size), B C N O (increasing first ionization enthalpy), I B r Cl (increasing electron gain enthalpy), L i N a K R b (increasing metallic radius)
