Select the related word/letters/number from the given alternatives.ASK : KAS :: SAW : ?

Let's analyze the relationship in the first pair:The word ASK is transformed into KAS.Position 1 (A) moves to position 2.Position 2 (S) moves to position 3.Position 3 (K) moves to position 1.Alternatively, the order of letters is reversed as the last letter becomes first, followed by the first and second letter ($3\to 1\to 2$).Applying the same pattern to SAW:Letter 1 = S, Letter 2 = A, Letter 3 = WFollowing the $3\to 1\to 2$ position shift:The 3rd letter (W) comes first.The 1st letter (S) comes second.The 2nd letter (A) comes third.Thus, SAW becomes WSA.
