We have to answer to this question by sorting out the options. Since Beethoven chooses to stay, we cannot claim that he dislikes the children - B is incorrect. It is also not evident that Beethoven wants to be somewhere else because we haven't got any information about this. Similarly, we don't know that he has got his own children or not. Therefore, A and C are incorrect options. The correct option is D because Beethoven stays to play for the children when they want him to stay.
