Solution:

(d) Sum of alphabets position in 1

^\st

row
= 1 + 4 + 1 + 3 + 2 + 2 + 4 + 3 + 3 = 23
Similarly, sum of digits in 2

^\nd

row
= 1 + 3 + 1 + 2 + 4 + 2 = 13
Since, these are prime numbers, so sum of all given and unknown alphabets in 3

^\rd

row should also be a prime no.
Thus, 3

^\rd

row = 1 + 2 + 3 + 4 + 4 + 3 + 1 + 1 = 19 (taking D option as correct).
No other option gives a prime value in such manner,
hence correct answer is (D).
