The best choice is option 3:

"Plants that are fertilized with fish meal will grow taller than plants that receive artificial fertilizer."

Why: it is specific and testable — it names the independent variable (type of fertilizer), the dependent variable (plant height), and predicts a direction (fish meal > artificial fertilizer).

If you want it even clearer for an experiment, add specifics and a null hypothesis, for example:

- Refined hypothesis: "Tomato plants fertilized with 10 g of fish meal per pot will grow taller over 8 weeks than tomato plants fertilized with an NPK artificial fertilizer at an equivalent nutrient rate, with all other conditions held constant."
- Null hypothesis: "There is no difference in mean height after 8 weeks between tomato plants fertilized with fish meal and those fertilized with the artificial NPK fertilizer."
