If ZERO is encoded as ADSN, then how do you encode STOP?
A.SPOT
B.TSPO✓ Correct
C.TSOP
D.POST
Explanation
Examining ZERO → ADSN: Z(+1)=A, E(−1)=D, R(+1)=S, O(−1)=N. So the rule is +1, −1, +1, −1 applied to alternating letters. Applying to STOP: S(+1)=T, T(−1)=S, O(+1)=P, P(−1)=O. So STOP → TSPO. The answer is TSPO.
