Answer:

P

Explanation:

we know that as we go forward of the period the first ionisation enthalpy increases and go down the group ionisation entahlpy is decreases. so,

atomic number of Na  = 11

    ,,          ,,        ,,  Ca  = 20

    ,,          ,,        ,,   Al  =  13

    ,,          ,,        ,,    P  =   15

hence the sequence will be, Ca < Na < Al < P
