Which of the following letters would come next in the series of letters?

Solution

In the given series from the end of the alphabet series, Z is the 1^st alphabet, W is the 4^th alphabet, R is the 9^th alphabet and K is the 16^th alphabet. Thus the next letter in the series will be the 25^th alphabet from the end or the second from the start. Hence, the next alphabet must be B. Thus (c) is the correct option.
