If 'TABLE' is coded as 'VCDNG', how is 'CHAIR' coded in the same language?

Apply a constant +2 shift to each character position to derive the target word from the source word.
Apply a constant +2 shift to each character position to derive the target word from the source word.
Analyze the Coding Pattern
Compare TABLE to VCDNG: T+2=V, A+2=C, B+2=D, L+2=N, E+2=G. The pattern is a consistent shift of +2 for every letter.
Apply Logic to CHAIR
Applying the +2 shift to each letter of CHAIR: C+2=E, H+2=J, A+2=C, I+2=K, R+2=T. The result is EJCKT.
B is incorrect because it changes the 4th letter to J instead of K. C is incorrect because it inserts an extra letter K into the sequence. D is incorrect because it changes the 5th letter to U instead of T.
A is correct because applying a consistent +2 shift to each letter of CHAIR (C+2=E, H+2=J, A+2=C, I+2=K, R+2=T) results in the string EJCKT.
For coding-decoding questions, write the numeric positions of letters (A=1, B=2, ... Z=26) to quickly identify arithmetic relationships between strings.
