Professor Atari is studying whether playing videogames that require mental rotation of visual images fosters success on spatial reasoning tests.  The best method for Professor Atari to use to be able to infer cause and effect would be to

A) randomly choose half of the participants to play videogames and the remaining half to play no videogames and later compare measures of spatial reasoning for each group.
B) select a group of children who already play a lot of videogames and a second group who never play video games and compare their scores of spatial reasoning.
C) calculate a correlation between children's scores of spatial reasoning and the number of hours of videogame play.
D) compare the number of hours of videogame play among children who score high on spatial reasoning tests with those who score low on spatial reasoning tests.
