Select the pair which follows the same pattern as that followed by the two set of pairs given below. Both pairs follow the same pattern. PTL : NRI AEX : YCV

In PTL:NRI, each letter moves back by 2 positions in the alphabet (P-2=N, T-2=R, L-2=J... wait L-2=J not I). Let me try: P→N(−2), T→R(−2), L→J... that doesn't give I. Try reverse: PTL reversed is LTP, not NRI. Another pattern: each letter +2 forward from NRI gives PTL (N+2=P, R+2=T, I+2=K)... not matching. For TVN:RTL — T-2=R, V-2=T, N-2=L ✓. This matches the −2 pattern.
