The correct option is B) to play the flute.
In english, play can be used to say you play an instrument or you are playing a game. However, in spanish, there are two different words for those actions.
You should use "tocar" when playing an instrument or a style of music. It can also mean "to touch".
For example:Me gusta tocar la guitarra
You should use "jugar" when you are refering to a game or a sport.
For example: Juego fútbol todos los días
