Solution

The correct option is D $N a < A l < M g < S i$
The first ionization potential of Na, Mg, Al, and Si are in the order,
$N a < A l < M g < S i$
On moving from left to right in a period, the ionization energy increases.
Al has lower ionization energy than Mg.
Al has valence shell electronic configuration $3 s^{2} 3 p^{1}$ .
Mg has valence shell electronic configuration $3 s^{2}$ .
Less energy is required to remove a p electron than filled s electron from the same principal quantum shell.
