Step-by-step explanation:

A testable question is one that can be answered through testing, experimentation, and observation in the natural world. Testable questions are made before observing the natural world and they help guide scientific investigations. They are answered by designing and conducting experiments to gather data and analyze results.

For example, a testable question could be: 'Does the amount of sunlight affect plant growth?' This question can be answered by setting up an experiment where plants are exposed to different amounts of sunlight and measuring their growth over a period of time.

Therefore, the correct statement is B. Testable questions are answered through testing how one thing will affect another thing.
