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 provides a testable prediction about the relationship between the independent variable (salt water) and the dependent variable (plant growth), making it suitable as a hypothesis.
