Select the option that is related to the third term in the same way as the second term is related to the first term.RADIUS : ARINSU :: SQUARE : ?

Let's analyze the transformation from RADIUS to ARINSU:Divide the word into pairs or look at individual positions:R $\to$ A (position shifted)Let's look at pairs: (R, A), (D, I), (U, S)In RADIUS, if we swap adjacent letters:RA $\to$ ARDI $\to$ ID? But we have IN. Let's see: D (+5) $\to$ I, I (+5) $\to$ N.US $\to$ SU.Let's double check this:1st and 2nd letters (R, A) swapped $\to$ A, R3rd and 4th letters (D, I) $\to$ D + 5 = I, I + 5 = N $\to$ I, N5th and 6th letters (U, S) swapped $\to$ S, ULet's apply this exact pattern to SQUARE:1st and 2nd letters (S, Q) swapped $\to$ Q, S3rd and 4th letters (U, A) $\to$ U + 5 = Z, A + 5 = F $\to$ Z, F5th and 6th letters (R, E) swapped $\to$ E, RCombining them gives: QSZFER
