The correct answer is True.
It is true that power is the ability to control the behavior of others with or without their consent.
When people have power, they can order. Order means that others need to obey. Power is the faculty of exercise the will of a person or a nation over their citizens. This concept could be seen during the monarchies in Europe or the dictators such as Joseph Stalin, Adolph Hitler, Benito Mussolini, or Francisco Franco. That is why they were dictators because they have the power to instill their will on people.
