Select the option that is related to the fifth term in the same way as the second term is related to the first term and fourth term is related to the third term.

PRAY : UWFD :: MONK : RTSP :: FAIT : ?

KFNY 

In this analogy, the 5 is added to the aplhanumeric value of each letter

For example, P has value 16, so 16 + 5 = 21

It becomes U

Thus PRAY corresponds to UWFD

Similarly, MONK corresponds to RTSP

To calculate the corresponding term to FAIT we write the values of each term 

F  A  I  T

6  1  9  20

Adding 5 to each,

11 6 14 25

K  F   N   Y

Thus, the term that replaces ? is KFNY
