this seem to be the case of ERB Duchenne ( upper trunk injury ) and two rami C5, C6 can be involve as there are separate choices its mean Q is asking which one among these two will first injured so it should be C5.

Erb or Klumpke palsy?

I think it's C5 and C6. think about it- the question says shouler depression. If you were to take the plexus and stretch it downward (depress it) you'd stretch the superior part of the plexus, i.e C5/6.

I'm just wondering that trapezius muscle move the shoulder upward and its nerve is CN XI. In this case which muscle doesn't work?
