Which orbitals of the hydrogen atom are degenerate for n=3? Which of the following orbitals are degenerate in the hydrogen atom with $n = 3$?
  
  A. II and III only;
  B. I and IV only;
  C. I, II, and IV only;
  D. II, III, and IV only;
  E. all.
  


The answer says its E. All of them.

First of all isn't there only 1 electron in hydrogen? And how could the $\mathrm{s}$ orbital be degenerate? Doesn't degenerate mean there are multiple places pairs of orbitals can be?

yes


  And how could the s orbital be degenerate? Doesn't degenerate mean there are multiple places pairs of orbitals can be?


"degenerate" means having the same energy.  "Degenerate" refers to a set of orbitals.  It doesn't make sense to say one orbital is degenerate. 

Solving the non-relativistic Schrodinger equation, all the orbitals for a given "n" are degenerate.  Energy only depends upon n. 

More complete consideration including relativity, spin and quantum electrodynamics shows that they are not all degenerate however.
