This is the kind of question that will widen the horizon in math since every choice can be Googled to find out more information.  We only need to, as a minimum, check out the date of the problem, and decide which is the good answer choice.
However, it is the intention of the question for the student to read about each problem.  Happy reading!

I was gonna say 'trisecting any angle' but it's not listed here and I've not heard of any of these other ones before.

@FFASinger 
Just to make sure you didn't get the wrong idea, @Kainui and I referred to $tri$section of an angle.  What's on your list is "bisection" of an angle, so they're not the same.
I suggest you google each choice and decide exactly which one belongs.
Post your answer for checking if you have done the research and still not sure.
