Rose's cuckoo clock is powered by a pendulum, which she has to push gently to the right or left every couple of days after it stops swinging. rose's clock is a perfect example of the fact that: a. energy is transferred to different forms. b. energy is created. c. energy can be destroyed in different forms. d. energy is released during a combustion reaction.

The correct option is A.
One of the fundamental principles that uphold the knowledge of chemistry is that energy can neither be created nor destroyed, but it can be transformed from one form to another form. This is called the law of conservation of energy. In the question given above, Rose is applying energy each time she push the swinging pendulum and the energy she applies is converted to kinetic energy, which the pendulum use to resume movement.
