Explanation
use H =( V+M -C+A ) / 2
WHERE V, = valance electron of central atom,
M is no of mono valent atom , ie halogen or alkali metal
C/A = charge on cation or anion ..
a = c and N acts as central atom , o is divalent ,so no need to count.
(6+2 ) /2= 4 , ( 7+ 1)/2 = 4,same for option d
(a) and (d)
Hence, both options (a) and (d) are correct.
