Scientific method is the best choice for testing a specific hypothesis.

Option C

Explanation:

Hypothesis is a proposed explanation for any phenomenon. It is an act or an assumption of statistical data. To test it, a scientific method is being required. The scientists are having many observations but cannot be explained with the available  scientific theories. It is something proposed for further research.

Hypothesis test mainly evaluates two statements about population data to know which statement best supported by sample data. If we want to make any proofs regarding the distribution of data whether one set of results are different from the other one, then we must rely on hypothesis test. This is how hypothesis test is being used. Other than scientific methods, it cannot be tested.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
