The challenge in applying utilitarianism is that (points : 1) it cannot distinguish among different kinds of pleasures. it is difficult to calculate the various benefits involved. it can lead to the tyranny of the majority. all of the above. none of the above.

Advanced by thinkers like John Stuart Mill and others, Utilitarianism is the philosophical principle that decisions should be guided by the goal of creating the greatest amount of good for the greatest amount of people. The problem with this philosophy is, firstly, that "good" is a matter of opinion. Secondly, creating a greater amount of good for a majority of people does exclude the minority, and just because people are in the minority doesn't mean they don't also deserve good. 

For that reason, it seems like "all of the above" is the best choice is "all of the above."

You could solve them by trying something new that everyone can agree on or make a decision too.
