RRB NTPC 2025 Graduate CBT 2 Question Paper PDF (10-Jul-2026) (Shift 1)
The correct answer is

Three

The full 20-letter series is indexed from 1 to 20.

Fifth from the right end is position 16, which is L.

Fourth from the left end is position 4, which is H.

Letters strictly between H (8th alphabet letter) and L (12th alphabet letter): I, J, K — a total of three letters.

Hence, there are three letters between the two identified letters.
