You realize its a binomial question, but because of the sample size, they use a normal approximation with mean ... and variance ....
Then the distribution of the sample mean has mean ... and variance (or standard deviation) ...
I take it you understand the usual null hypothesis test for a normal distribution? If so, once you have the above sorted, you should be able to undertand the MS?

Yes, it is part c that I do not get.

After that line, its just a normal distribution null hypothesis test, which I presume you understand? Line 3 appears a bit random (completely wrong for the question) though. Lines 2 and 4+ are fine and totally unrelated to line 3.
