The elements in first row are

A S 23

C U 29

E W 31

If we look closely, the pattern followed is

A+2 = C, C+2 = E

S+2 = U, U+2 = W

23,29,31 are the consecutive prime numbers.

Similarly, this pattern is followed in the second row as well

G Y 37

I A 41

K C 43

G+2 = I, I+2 = K

Y+2 = A, A+2 = C

37,41,43 are consecutive prime numbers.

Then, in third row.

M E 47

M+2 = O

E+2 = G

47 and next is 53

Thus, Option C is the correct answer.
