Answer
Correct Answer: he is capable at
Explanation
Introduction / Context:This question checks the correct preposition after “capable.” Some adjectives require fixed prepositions, and “capable” is one of them.
Given Data / Assumptions:
- The adjective is “capable.”
- The structure used is “capable at doing …,” which is suspect.
- The intended meaning is possession of ability or competence.
Concept / Approach:The fixed preposition with “capable” is “of,” followed by a gerund or noun: “capable of doing something.” “Capable at” is incorrect in standard English.
Step-by-Step Solution:
Identify the adjective-preposition pattern: “capable of.”Spot the error: Segment B uses “capable at.”Check remaining segments for correctness: C and D are acceptable phrases.Verification / Alternative check:Corrected sentence: “Don’t go by his appearance; he is capable of doing any work without any hesitation.”
Why Other Options Are Wrong:
- A: “Don’t go by his appearance;” is idiomatic and correctly punctuated with a semicolon.
- C/D: Grammatically sound.
Common Pitfalls:Confusing “capable of” with “good at.” We say “good at doing X” but “capable of doing X.”
Final Answer:he is capable at
