Question

Select the letter-cluster from among the given options that can replace the question mark (?) in the following series.

BRF, EUH, HXJ, KAL, ?

1. A. NMB
2. B. NKH
3. C. NHG
4. D. NDN (Correct answer)

Correct Answer

Option D — NDN

Detailed Solution & Explanation

The correct answer is NDN.

Key Points

• Resolve each column: Position 1 B→E→H→K→N (+3).
• Position 2 R→U→X→A→D (+3, wrapping past Z).
• Position 3 F→H→J→L→N (+2).
• The next cluster is therefore N D N.
• The wrap in the middle column (X→A→D) is where errors creep in — convert to numbers (mod 26) so the wrap is mechanical rather than guessed.
