Solution

The correct option is D None
All three $M g$ , $C$ and $N e$ have $2 n d$ ionisation potential greater than $1 s t$ ionisation potential.
This is the general trend shown by most element that $1^{s t} I P < 2^{n d} I P < 3^{r d} I P <$ and so on.
Hence, option D is correct.

Which of the following element has 2ndIP<1stIP?

The correct option is D NoneAll three Mg, C and Ne have 2nd ionisation potential greater than 1st ionisation potential. This is the general trend shown by most element that 1stIP<2ndIP<3rdIP< and so on.Hence, option D is correct.
