The correct answer is

OCP

To find the missing letter set in the series "UMD, ZQG, EUJ, JYM, ?", we need to observe the pattern and logic based on the positions of the alphabets in the English alphabetical order.

Let's analyze the sequences step-by-step:

  1. The first letter series: U, Z, E, J
    • U (21st letter) to Z (26th letter): +5
    • Z (26th letter) to E (5th letter): -21 (Consider Z as 26 and then loops back to start, so 26 + 5 = 31, 31 - 26 = 5)
    • E (5th letter) to J (10th letter): +5
    • Following the pattern, J (10th letter) + 5 = O (15th letter).
  2. The second letter series: M, Q, U, Y
    • M (13th letter) to Q (17th letter): +4
    • Q (17th letter) to U (21st letter): +4
    • U (21st letter) to Y (25th letter): +4
    • Following the pattern, Y (25th letter) + 4 = C (3rd letter, as it loops back to start).
  3. The third letter series: D, G, J, M
    • D (4th letter) to G (7th letter): +3
    • G (7th letter) to J (10th letter): +3
    • J (10th letter) to M (13th letter): +3
    • Following the pattern, M (13th letter) + 3 = P (16th letter).

Therefore, the missing set of letters following the given pattern is OCP.

Verifying the answer against the options:

  • Option 1: NDO - Does not follow the derived pattern.
  • Option 2: PDP - Fails the pattern check.
  • Option 3: NBQ - Incorrect, doesn't match the derived letters OCP.
  • Option 4: OCP - Correct as per our derivation.

Hence, the correct answer is OCP.
