OT11 is related to PU15 in a certain way. In the same way, WB21 is related to XC25. To which of the following is DI31 related, following the same logic?

​OT11 → PU15, WB21 → XC25

DI31 → ?

Logic: ​Each letter is shifted +1 forward, and the number is increased by +4.​

O+1 → P

T+1 → U

11+4 → 15

WB21 → XC25:

W +1 → X

B +1 → C

21 +4 → 25

Similarly,

DI31 → ?:

D +1 → E

I +1 → J

31 +4 → 35

So, DI31 → EJ35

Thus, the correct option is: (c)
