The best hypothesis for the experiment would be:
**"If salt water is used to water plants, then the plants will not grow as tall as those watered with tap water."**
This statement clearly establishes a cause-and-effect relationship, predicting the outcome of the experiment based on the manipulation of the independent variable (salt water) and the dependent variable (plant growth).
**"If salt water is used to water plants, then the plants will not grow as tall as those watered with tap water."**
