Which of the following options should come in place of the question mark (?) in the given series based on the English alphabetical order?

ACDF, GIJL, MOPR, SUVX, YABD,?

Correct option is B

Given = ACDF, GIJL, MOPR, SUVX, YABD,?

Identify the pattern.

• The first letter of each group follows a fixed pattern.

and the letters of term shifts by positions - 

A + 2 = C, C + 1 = D, D + 2 = F

• The starting letter of each group follows the sequence:
  A → G → M → S → Y → ?

Observe the positions of these starting letters:

• A (1) → G (7) → M (13) → S (19) → Y (25).

The sequence increases by 6 positions each time.

• Starting from Y (25), add 6:
  25 + 6 = 31.
  Since the alphabet wraps around, 31 - 26 = 5, which corresponds to E.

Determine the letters.

Starting with E and following the same logic (letters 2 positions apart):

• Start at E (5).
• Add 2 → G (7).
• Add 1 → H (8).
• Add 2 → J (10).

Thus, the next group is EGHJ.

Final Answer:

B) EGHJ
