I believe your answer is C.

Explanation:

First of all, if you pay attention to the details of the question it states that scientific hypothesis should be specific and demonstrate the relationship between the independent and dependant variable.

Answer A - Does demonstrate the relationship between the independent and dependant variable. but it's not very specific. Thus it is Not the answer.

Answer B - is not specific or demonstrates the relationship between the independent and dependant variable. Thus it is Not the right answer.

Answer C - Fits the criteria as it is specific, and demonstrates the relationship between the independent and dependant variable. Thus it is the Right answer

Answer D - is in the same category as B so again is Not the right answer.

Therefore your only option is C. Your welcome, and have a wonderful day
