The first ionisation energy of Al is smaller than that of Mg because :...
Penetration of p-subshell electron is less than s-subshell electrons. In case of Mg, the first electron is to be removed from completely filled 3s2 valence shell configuration as compared to partially filled 3p1 of Al. These two factors collectively accounts for the higher ionisation energy of Mg than that of Al. Therefor, (C) option is correct.

The first ionisation energy of Al is smaller than that of Mg because :...
Penetration power is the ability of orbital electrons to be attracted by nucleus. the penetration power of s orbital is greater than that of p orbital. in Mg last electron is present in the orbital is s orbital so their electrons are easily attracted by nucleus and in case of Al last electron is present in the p orbital so penetration power of p orbital is less than s orbital plus shielding effect of s orbital also present so electrons are not that strongly attracted by nucleus as compared to Mg therefore decrease in enthalpy occurs
