Correct Answer

✅ Option d — NPSV

All Options:

  • ACEHL
  • BKMPT
  • COQTX
  • DNPSV

Detailed Solution & Explanation

Let's analyze the letter position differences in each option using alphabetical values (A=1,B=2,…,Z=26\displaystyle \text{A}=1, \text{B}=2, \dots, \text{Z}=26):
- **CEHL**:
C=3,E=5,H=8,L=12\text{C}=3, \text{E}=5, \text{H}=8, \text{L}=12
Differences: 5−3=+2, 8−5=+3, 12−8=+4\text{Differences: } 5-3 = +2,\ 8-5 = +3,\ 12-8 = +4
- **KMPT**:
K=11,M=13,P=16,T=20\text{K}=11, \text{M}=13, \text{P}=16, \text{T}=20
Differences: 13−11=+2, 16−13=+3, 20−16=+4\text{Differences: } 13-11 = +2,\ 16-13 = +3,\ 20-16 = +4
- **OQTX**:
O=15,Q=17,T=20,X=24\text{O}=15, \text{Q}=17, \text{T}=20, \text{X}=24
Differences: 17−15=+2, 20−17=+3, 24−20=+4\text{Differences: } 17-15 = +2,\ 20-17 = +3,\ 24-20 = +4
- **NPSV**:
N=14,P=16,S=19,V=22\text{N}=14, \text{P}=16, \text{S}=19, \text{V}=22
Differences: 16−14=+2, 19−16=+3, 22−19=+3\text{Differences: } 16-14 = +2,\ 19-16 = +3,\ 22-19 = +3

All letter groups except **NPSV** follow the +2,+3,+4\displaystyle +2, +3, +4 position difference pattern. Therefore, **NPSV** is the odd one out.

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