Hi, I did this question before and I stumbled upon it wondering what on earth was it on about! If you look at it though it is really simple...
A tennis ball can not diffract through a slit, so its not that one.
A tennis ball is a particle and so will display their properties, so it's not that one.
A tennis ball under no circumstances will display wave properties and so this one is the answer.
Also particles with mass cannot travel at the speed of light and so this statement is incorrect also :biggrin:
