Question

a hypothesis is a knowledgeable statement that introduces your experimental question and...
disproves an expected result.
proposes what you think wont happen.
proposes an expected result.
calculates results.

Explanation:

A hypothesis in scientific research (relevant to Natural Science subfields like Biology, Physics, etc.) is a statement that predicts or proposes the expected outcome of an experiment. It doesn't disprove an expected result (that's more of a conclusion after testing), it's not about proposing what won't happen (that's a negative hypothesis but the main idea is a positive prediction of what is expected), and it doesn't calculate results (calculations are part of data analysis). So the correct option is the one that says it proposes an expected result.

Answer:

C. proposes an expected result. (Note: Assuming the options are labeled A, B, C, D with the third option being C. If the original labeling is different, adjust the identifier accordingly, e.g., if the third option is labeled as "3. proposes an expected result", then the answer would be "3. proposes an expected result".)
