Observe the simple +1 shift pattern for each letter in the sequence: T(+1)=U, A(+1)=B, B(+1)=C, L(+1)=M, E(+1)=F.
Observe the simple +1 shift pattern for each letter in the sequence: T(+1)=U, A(+1)=B, B(+1)=C, L(+1)=M, E(+1)=F.
Analyze the coding pattern
Compare TABLE to UBCMF: T(20)+1=U(21), A(1)+1=B(2), B(2)+1=C(3), L(12)+1=M(13), E(5)+1=F(6). The rule is each letter shifts by +1.
Apply the pattern to CHAIR
C(3)+1=D(4), H(8)+1=I(9), A(1)+1=B(2), I(9)+1=J(10), R(18)+1=S(19). Mapping these results in the code DIBJS.
B: DIBSJ has the last two letters swapped incorrectly. C: DJBIS has the second and third letters incorrect. D: DIBJS is a duplicate of A (as provided in the prompt options, both A and D are identical).
A is correct because applying the +1 alphabetical shift to each letter of CHAIR results in DIBJS.
In coding-decoding questions, always check the first two letters first; if they match your pattern, you can often eliminate options instantly to save time.
