SUWY is related to ZXVT in a certain way based on the English alphabetical order. In the same way, JLNP is related to QOMK. To which of the following is ACEG related, following the same logic?
DHBF
HFDB
BDFH
FHBD
HFDB
Observe the reverse alphabet order pairs: S-Z, U-X, W-V, Y-T is not the pattern; rather, it is a combination of shifting and reversing. The actual logic is mapping the first half to the last half using reversed positions.

Analyze the first pair (SUWY to ZXVT)
Map letters to positions: S(19), U(21), W(23), Y(25). Target: Z(26), X(24), V(22), T(20). The logic is to increment the first letter to Z(S+7), and then reverse the alphabetical sequence decreasing by 2 (26, 24, 22, 20).
Identify the uniform logic
Looking at both sets: SUWY (19, 21, 23, 25) тЖТ ZXVT (26, 24, 22, 20) and JLNP (10, 12, 14, 16) тЖТ QOMK (17, 15, 13, 11). Logic: Start with (Last letter of input + 1) and then count backwards by 2.
Apply logic to ACEG
Input ACEG: A(1), C(3), E(5), G(7). The last letter is G(7). The first letter of the result is G+1 = H(8). Counting backwards by 2: H(8), F(6), D(4), B(2). Result is HFDB.
A: DHBF does not follow the decreasing sequence starting from H. C: BDFH is the original sequence in reverse order, not following the decrement rule. D: FHBD starts with F instead of H.
B is correct because the pattern requires taking the last letter of the sequence, adding 1, and then forming a sequence of four letters in decreasing alphabetical order by 2.
When faced with letter analogies, always write down the numerical position of each letter; patterns like +n/-n or reverse sequences become immediately visible.
