Statement Analysis:
The question asks which statement is incorrect about an object that starts to fall freely. Let's analyze each statement:

A) Its potential energy is increased and kinetic energy is decreased.
B) Its kinetic energy is increased and potential energy is decreased.
C) Potential energy remains unchanged.
D) Kinetic energy remains unchanged.

Explanation:
When an object starts to fall freely, it experiences a change in its energy state. Let's discuss each statement to determine which one is incorrect:

A) Its potential energy is increased and kinetic energy is decreased:
This statement is correct. As the object falls, its height decreases, resulting in a decrease in potential energy. At the same time, its speed increases, leading to an increase in kinetic energy.

B) Its kinetic energy is increased and potential energy is decreased:
This statement is correct. As stated above, the object's potential energy decreases due to the decrease in height. Simultaneously, its speed increases, resulting in an increase in kinetic energy.

C) Potential energy remains unchanged:
This statement is incorrect. When an object falls freely, its potential energy decreases due to the decrease in height. The potential energy is converted into kinetic energy as the object gains speed.

D) Kinetic energy remains unchanged:
This statement is incorrect. As the object falls freely, its speed increases, leading to an increase in kinetic energy. Therefore, the kinetic energy of the object changes.

Conclusion:
After analyzing each statement, we find that the incorrect statement is C) Potential energy remains unchanged. When an object starts to fall freely, its potential energy decreases while its kinetic energy increases. Therefore, option C is the correct answer.
