What is a scientific hypothesis?

A. A collection of data that generates a scientific observation

B. A final decision that describes a scientific model

C. A rigorous procedure that produces scientific data

D. A statement that tries to answer a scientific question

The answer is D. A hypothesis is a statement that tries to answer is question but has not been proven to be correct yet. It's not a conclusion or a final decision; it's not a procedure, but simply a statement; it's also not a collection of data, which should probably be part of the procedure. After making the hypothesis, one can carry out these processes to testify that hypothesis.

The best answer is

D) A statement that tries to answer a scientific question

A hypothesis is described by the definition above. It is where we start when trying to figure out how something in science works the way it does. We then test the hypothesis through experimentation and make conclusions regarding whether or not the hypothesis is correct.
