I am writing a report on an activity in a nursery school.
A child is playing with a jigsaw puzzle with a boy on it. Can you please help me to correct this last sentence which does not sound natural to me? I tried to jot down some options but I don't think the situation is improving

a) A child is playing with a boy puzzle
b) A child is playing with a puzzle with a boy on it
c) A child is playing with a puzzle with a boy in it
d) ????
Thank you for your help!
