Correct answer: D
CONCEPT
In alternating-shift coding, the same ordered sequence of letter movements is repeated at corresponding positions of every word.
Each letter is shifted independently, and positions beyond Z or before A wrap around the alphabet when needed.
APPLICATION
Compare SLIGHT with UJKEJR to obtain the position-wise shifts:
S → U is +2, L → J is −2, I → K is +2, G → E is −2, H → J is +2, and T → R is −2.
The repeating rule is therefore +2, −2, +2, −2, +2, −2.
Apply it to GROUND: G → I, R → P, O → Q, U → S, N → P, and D → B.
CROSS-CHECK
Reading the transformed letters in order gives IPQSPB. Applying the inverse shifts −2, +2, −2, +2, −2, +2 to IPQSPB returns GROUND, confirming the result.
Result: IPQSPB
