Which best defines a hypothesis?

Explanation:
A hypothesis is a proposed, testable statement about observations that makes a prediction you can check with experiments. It is not a proven fact, since it can be tested and potentially shown false. It is not a theory, which is a broad, well-supported account that ties together many observations. It is not the result of an experiment; it’s the idea you set up to test. Example: If a plant receives more sunlight, it will grow taller. You can test this by growing plants with varying light levels and measuring their growth.
