A hypothesis is when you make an educated guess before you complete the experiment. It is basically an inference on what might happen next. So a conclusion made based on facts.
Your answer would be C because A affects the natural environment and can cause harm to it, B would affect the surrounding animal population and cause imbalances in biodiversity if they are not able to eat the foods they are used to, and D is not much of a benefit since you are losing the flavor that is naturally in the plants.
