Explanation:

In scientific decipline, the hypothesis is a tentative statement which is produced by the method of prediction and assumption based on direct observation of the natural phenomena or event. It can be tested by using the experimental methodology.

Theory is a explaination for the cause of natural event or phenomena. This is based on the evidences obtained after experimental trials. A hypothesis can be used for generation of theory. A theory is more explanatory approach because of the details and evidences than hypothesis. Hence, c is the correct option.
