Odd One Out — Among the 4-letter strings TPOC, BKDF, OLTF, and BILQ, detect the one that does not contain any vowel (or equivalently, differs by vowel presence).
Correct Answer: BKDF
Introduction / Context:Letter-classification items commonly use vowel vs consonant structure as an underlying rule. The task is to find the single string that breaks or uniquely satisfies the rule.
Given Data / Assumptions:
- Strings: TPOC, BKDF, OLTF, BILQ.
- Vowels considered: A, E, I, O, U.
Concept / Approach:Check each string for the presence or absence of vowels.
Step-by-Step Solution:TPOC: contains O (a vowel).BKDF: B, K, D, F are all consonants; no vowel present.OLTF: contains O (a vowel).BILQ: contains I (a vowel).Exactly one string has no vowel: BKDF.
Verification / Alternative check:Re-scan each letter set; only BKDF lacks A, E, I, O, U.
Why Other Options Are Wrong:
- TPOC: has O.
- OLTF: has O.
- BILQ: has I.
Common Pitfalls:Overlooking the letter I in BILQ or treating Y as a vowel in this context.
Final Answer:BKDF
