Jobi read in his science textbook that when a laser is shined into a diamond in a dark room, the diamond will scatter the light, throwing many separate, focused beams of light on the walls and ceiling.

Jobi decided that his hypothesis and experiment were a waste. Was Jobi correct about this?A.No; his hypothesis was useless, but his experiment was valuable.

B.No; hypotheses are valuable whether or not they are correct. C.Yes; he chose an untestable hypothesis. D.Yes; spending time on an experiment that fails is a waste.
