Detailed Solution & Explanation

To find the next term in the alphabet sequence ALN,DNP,GPR,?\displaystyle ALN, DNP, GPR, ?, we analyze the alphabetical progression of each of the three letter positions separately (where A=1,B=2,…,Z=26\displaystyle A = 1, B = 2, \dots, Z = 26):

1. **First Letter Progression:**
- A→D→G→?\displaystyle A \to D \to G \to ?
- Alphabetical positions: 1→4→7→?\displaystyle 1 \to 4 \to 7 \to ?
- The pattern is a constant increase of +3\displaystyle +3: 7+3=10\displaystyle 7 + 3 = 10, which corresponds to **J**.

2. **Second Letter Progression:**
- L→N→P→?\displaystyle L \to N \to P \to ?
- Alphabetical positions: 12→14→16→?\displaystyle 12 \to 14 \to 16 \to ?
- The pattern is a constant increase of +2\displaystyle +2: 16+2=18\displaystyle 16 + 2 = 18, which corresponds to **R**.

3. **Third Letter Progression:**
- N→P→R→?\displaystyle N \to P \to R \to ?
- Alphabetical positions: 14→16→18→?\displaystyle 14 \to 16 \to 18 \to ?
- The pattern is a constant increase of +2\displaystyle +2: 18+2=20\displaystyle 18 + 2 = 20, which corresponds to **T**.

Combining the three letter positions, the next term in the sequence is **JRT**.

*Note on Answer Key Discrepancy:* The textbook/exam answer key lists **Option A** (KLN\displaystyle KLN) as the correct answer. However, KLN\displaystyle KLN has no logical alignment with the shifts observed in the sequence, whereas JRT\displaystyle JRT follows a strict, consistent mathematical progression. This represents a typographical error in the official answer key, and the correct option is **Option B**.

Hence, **Option B** is the correct answer.
