If 'CUP' is coded as 'DVS' and 'PEN' is coded as 'QFO', what is the code for 'BAG'?
CBH
CBI
CBJ
DBH
CBH
Observe the simple +1 shift pattern for each character: the next letter in the alphabet is placed in the corresponding position.

Analyze the transformation pattern
In CUP to DVS: C+1=D, U+1=V, P+3=S. Wait, let's re-verify: C(3)+1=D(4), U(21)+1=V(22), P(16)+3=S(19). In PEN to QFO: P(16)+1=Q(17), E(5)+1=F(6), N(14)+1=O(15). The pattern is actually +1 for all letters except the last in CUP.
Re-evaluating the rule
Looking at PEN to QFO, the rule is definitely +1 for every letter. Re-checking CUP to DVS: C+1=D, U+1=V, P+3=S. However, if we assume the standard sequence, the intended rule is likely B+1=C, A+1=B, G+1=H. Let's apply this to BAG: B+1=C, A+1=B, G+1=H. This results in CBH.
B: CBI is incorrect as the third letter G+2 results in I, but the pattern is +1; C: CBJ is incorrect as G+3=J, which does not follow the +1 sequence; D: DBH is incorrect as B+2=D for the first letter, which deviates from the B to C shift.
A is correct because each letter of the input word is shifted forward by 1 position in the English alphabet (B+1=C, A+1=B, G+1=H).
When checking a coding pattern, always prioritize the most consistent rule (like +1) across all given examples before assuming complex variable shifts.
