Which example describes voluntary muscle movement?

You didn't list the examples, but a voluntary movement is a movement you DECIDE to do. You decide to wave, shake someone's hand, kick a ball, walk, etc.

Involuntary movements are movements that you cannot decide to do or to control. Like your heartbeat, digesting food, eye twitching, etc.

One example of something that could potentially be both is breathing. You can't stop your breathing while you are sleeping (involuntary) but you can breathe if you want to (voluntary), you can take a breath in right now.

I hope this helps!
