In a certain code DRAUGHT is written as CQBVHIU and CONCISE is written as BNODJTF. How will PROBLEM be written in that code?

Information Given:
DRAUGHT → CQBHVHIU
CONCISE → BNODJTF
Find: PROBLEM → ?

Logic:
First 2 letters −1, remaining letters +1

Check:

D-1→C, R-1 →Q, A+1→B, U+1→V, G+1→H, H+1→I, T+1→U 

​CONCISE → BNODJTF
C-1→B, O-1→N, N+1→O, C+1→D, I+1→J, S+1→T, E+1→F 

Now PROBLEM:
P → O (−1)
R → Q (−1)
O → P (+1)
B → C (+1)
L → M (+1)
E → F (+1)
M → N (+1)

Final Answer:
OQPCMFN

Final Correct Option:
C
