From the words or group of words lettered A to D, choose the one that best completes the sentence.
My mother was pleased ... me when she learnt of my success.

Answer Details

The correct option to complete the sentence is "with". The sentence means that the speaker's mother was happy about their success, so the appropriate preposition to use after "pleased" is "with".
