Solution

The error relates to Conditional Sentence Structure (Third Conditional). Rule for Third Conditional: If + Past Perfect, Subject + would have + past participle Incorrect structure in the sentence: If the organisation would have implemented stronger security protocols earlier In conditional clauses beginning with if, we do not use “would have”. Correct structure: If the organisation had implemented stronger security protocols earlier, it could have prevented the massive data breach. Thus, the error lies in part (a). Option Analysis A. a – Incorrect because “would have implemented” should be “had implemented.” B. b – Correct modal perfect structure (could have prevented). C. c – Grammatically correct noun phrase. D. d – Correct relative clause modifying “breach.” E. e – Incorrect because an error exists in the sentence.
