Yes indeed, very solid point here
C.
The introductory phrase, "Crowned with a wreath of olive leaves", is correctly separated by a comma.
The answer is B.
It's not A because the sentence involves the words "very stressful", which is an opinion.
It's not C because saying that taxpayers "should expect" is also an opinion.
It's not D because it's saying you "should always", which is an opinion.
Hope this helped!
