Answer: B) HYPOTHESIS
Step-by-step explanation:
A hypothesis is a provisional affirmation about the connection between two or more variables.
For this example, the problem would be "I am missing the ball". The hypothesis would be that the reason behind me missing the ball is that I am not keeping my eyes on it.
A way to test the hypothesis would be to compare the results with and without keeping sight of the ball. Based on the hypothesis, the prediction would be: If I keep my eyes on the ball, I will not miss it, whereas if I loose sight of the ball I will miss it.
