Hello!

The correct answer is A. A system is a group of objects analyzed as one unit.

We know this because all systems are NOT made by humans, there are numerous ways to define the boundaries of one, and the energy is not necessarily conserved. The parts of a system are analyzed as being apart of that group, which makes A the only correct and rational answer.

I hope I helped! :)
