Answer:
First add a variation of animation skills that could possibly prove useful out in the industry, the plan is to animate a dog (Quadruped) running, walking and interacting with something. Also plan to animate a biped lifting a heavy object, jumping a gap, talking (lip sync) and also a character animation piece which will involve a character interacting with a ball playing basketball. Here I have a few videos which I have watched carefully for inspiration and reference on the way a dog’s body moves.

I believe the best answer for this question is D, "rhythm." Let us consider what each of these terms mean. "Focal emphasis" means the element that draws your attention the most. "Contrast" involves elements that are very different from each other, usually juxtaposed together to create an effect. "Rhythm" means repetition, arrangement, or flow. "Composition" means the way something is composed. Hope this helps.
