Detailed Solution & Explanation

We are given the letter series: ABD, DGK, HMS, MTB, SBL, ?
Let's analyze each letter of the terms by their alphabetical positions:
1. **First Letter:** A, D, H, M, S
- Alphabetical positions: A (1), D (4), H (8), M (13), S (19).
- Differences: +3,+4,+5,+6\displaystyle +3, +4, +5, +6.
- The differences increase by 1\displaystyle 1 each time. The next difference is +7\displaystyle +7.
- The next letter position is 19+7=26\displaystyle 19 + 7 = 26, which is **Z**.
2. **Second Letter:** B, G, M, T, B
- Alphabetical positions: B (2), G (7), M (13), T (20), B (28 or 2).
- Differences: +5,+6,+7,+8\displaystyle +5, +6, +7, +8.
- The differences increase by 1\displaystyle 1 each time. The next difference is +9\displaystyle +9.
- The next letter position is 2+9=11\displaystyle 2 + 9 = 11, which is **K**.
3. **Third Letter:** D, K, S, B, L
- Alphabetical positions: D (4), K (11), S (19), B (28 or 2), L (38 or 12).
- Differences: +7,+8,+9,+10\displaystyle +7, +8, +9, +10.
- The differences increase by 1\displaystyle 1 each time. The next difference is +11\displaystyle +11.
- The next letter position is 12+11=23\displaystyle 12 + 11 = 23, which is **W**.
Combining the components: Z + K + W = **ZKW**.
Hence, **Option D** is the correct answer.
