The thief was caught and the police . . . . . . . . the stolen goods from him. A. concerned B. attained C. recovered D. recover

The correct answer is C. recovered.

The other options are incorrect because:

• A. concerned means “to feel worried or troubled about something.”
• B. attained means “to achieve or reach a particular level or standard.”
• D. recover means “to get back to a normal state after an illness or injury.”

In the sentence, the police recovered the stolen goods from the thief. This means that they found the goods and took them back from the thief.
