C, G, K, O. ?, W

A.

U

B.

S

C.

T

D.

R

Correct option is B

The given series is: C, G, K, O, ?, W
To find the pattern, look at the positions of each letter in the alphabet:
· C is the 3rd letter.
· G is the 7th letter.
· K is the 11th letter.
· is the 15th letter.
The pattern here is that each letter is 4 positions ahead of the previous letter.
Following this pattern:
O (15th letter) + 4 = S (19th letter)
Thus, the missing letter is S.
Correct answer: (b) S.
