If different types of leaves are exposed to low temperatures, then they will change colors.

Answer 1

The statement that best represents a proper hypothesis is:

**If different types of leaves are exposed to low temperatures, then they will change colors.**

This statement clearly presents a testable prediction based on the relationship between the independent variable (low temperatures) and the dependent variable (change in color of leaves). Hypotheses generally take the form of "if, then" statements, which this one does.
