Analysis of the first letter pair "TUV" and "VYB" reveals the following shifts:- T to V: A forward shift of 2 positions.- U to Y: A forward shift of 4 positions.- V to B: A forward shift of 6 positions.Applying these sequential shifts (2, 4, 6) to the letters in "PRA" yields:- P shifted by 2 positions results in R.- R shifted by 4 positions results in V.- A shifted by 6 positions results in G.Consequently, "PRA" transforms into "RVG". The correct option is (B).
