D. Parallelism
Based on Your dictionary, it states: “Parallelism has slightly different meanings, depending on the context, but it’s about balancing the weight or structure of ideas and phrases. In rhetoric, parallelism means balancing two or more ideas or arguments that are equally important.”
I would say wait until the teacher finishes saying what needs to be said try not to interrupt them mid-sentence or if they keep rambling on and on , simply just raise you hand and say excuse me (teachers name) sorry to interrupt but could you help me on this or take a second to explain this for me. Hope this helped
