In letter analogy, each letter shifts by a fixed value in the alphabet.Explanation:For ACID→CAKB: the 1st and 3rd letters increase by +2, while the 2nd and 4th letters decrease by −2.A+2=C, C−2=A, I+2=K, D−2=B.Apply the same rule to AWAY:A+2=CW−2=UA+2=CY−2=WSo, AWAY→CUCW.Answer:CUCW is the correct answer.
