Classification – Odd one out (vowel vs consonants): Which letter is different from the others: A, D, F, K?
Correct Answer: A
Introduction / Context:This is another vowel-consonant discrimination task. Three of the listed letters are consonants; one is a vowel. Identify the vowel to find the odd one out.
Given Data / Assumptions:
- A — vowel.
- D — consonant.
- F — consonant.
- K — consonant.
Concept / Approach:Use the standard vowel set {A, E, I, O, U}. Only A among the given letters is a vowel; the others are consonants. Hence, A is the outlier.
Step-by-Step Solution:1) Mark A as vowel; D/F/K as consonants.2) Pick A as the single vowel.
Verification / Alternative check:Phonetic classification aligns with the orthographic classification; there is no ambiguity.
Why Other Options Are Wrong:D/F/K share “consonant” status and thus belong together.
Common Pitfalls:Overcomplicating with alphabet positions; the simplest category works here.
Final Answer:A
