Show the answer and explanation
CorrectNot quiteAnswer C
Correct answer: C
Explanation
Shifting TIGER does not give SFHJU directly, so reverse it first: REGIT.
REGIT to SFHJU: R to S, E to F, G to H, I to J, T to U, a shift of +1.
HORSE reversed is ESROH; +1 gives F, T, S, P, I.
The code is FTSPI.
Worth noting
IPSTF shifts HORSE by +1 but forgets to reverse it. DRQNG reverses and then shifts the wrong way.
