The question doesn't seem to make sense.
If it is given that it took 10 seconds to spin around, the pole must have moved in a 1-lt-yr arc. (That's C = pi*D = pi*2-lt-yr) That's pretty fast!
If this is given, then the pole spun around and did not break and made the arc. Given.
Answer a) asks if it doesn't violate any laws....wha?! Of course it does, so this must be wrong.
Answer b) states that the pole can't go faster than the speed of light...which it can't...but, IT JUST DID in the given part of the problem!..so this must be wrong.
Answer c) is correct by the process of elimination.
