B

Explanation:

Answer 2

Answer:

Problem on periodic table:

As the periodic table rule of ionisation potential,

Moving from left to right of the periodic table increases the ion potential or energy from left to right and decreases ion potential or energy by moving from top to bottom.

Na(11),Mg(12),Al(13) and Si(14) are going in this way so Since it is located along the stage i.e. from left to right, the ionization energy will increase as it increases.

So ionisation potential is increasing in this way :Na<Mg<Al<Si. As your question option (B) is right answer.
