Error spotting — Choose the erroneous part (A/B/C) or D if correct: 'He ensured his bank manager / that he would soon / repay the loan. / No error.' Focus on precise verb choice ('assured' vs 'ensured') in business English.

Concept/Approach (diction)
Ensure = make certain that something happens; it does not take a personal object. Assure = tell someone confidently to remove doubt. Therefore, we assure someone and ensure something.

Step-by-step correction
A: 'He ensured his bank manager' → 'He assured his bank manager …'Corrected sentence: 'He assured his bank manager that he would soon repay the loan.'

Common pitfalls
Using 'ensure' with human objects; confusing ensure/assure/insure.

Final Answer
A — Replace 'ensured' with 'assured'.
