Answer
Correct Answer: not have
Explanation
Introduction / Context:The item tests the correct construction with the modal “ought to.” The sentence is split into four parts; pick the incorrect fragment.
Given Data / Assumptions:
- “Ought to” must be followed by a bare infinitive.
- In perfect infinitive constructions, use “ought not to have + past participle.”
Concept / Approach:The fragment “not have” is missing “to.” The correct negative is “ought not to have done …”.
Step-by-Step Solution:
A: “He ought” — start of a modal phrase; expects “to.”B: “not have” — error; should be “not to have.”C: “done such a” — correct determiner phrase with past participle.D: “filthy thing.” — grammatical object phrase.Verification / Alternative check:
Corrected: “He ought not to have done such a filthy thing.”Why Other Options Are Wrong:
Only B contains the structural omission; A, C, and D are fine in context.Common Pitfalls:
Dropping “to” after “ought,” especially in negatives and questions.Final Answer:not have
