Correct answer: B
Concept
Position-wise letter coding applies a fixed operation to each letter according to its place in the word. To infer the rule, compare corresponding letters and record their alphabetic shifts.
Application
SCHOLAR → TEKSQGY gives S→T (+1), C→E (+2), H→K (+3), O→S (+4), L→Q (+5), A→G (+6), and R→Y (+7). Thus the nth letter is advanced by n positions.
Apply the first five shifts to GREEN: G+1=H, R+2=T, E+3=H, E+4=I, N+5=S.
Cross-check
The shifts from GREEN to HTHIS are +1, +2, +3, +4, and +5, matching the first five positions of the inferred rule. Therefore the code is HTHIS.
