My reasoning:
1.A because it’s the only one to take 2 arguments. I thought about ‘trigonometric operations’, too, but I wouldn’t call ->DEG a trig operation. I now realize that probably E is the correct answer, as indeed the 4 others are on the keyboard.
2.C doesn’t alter the stack
3.D isn’t a test
4.D accepts only integers.
5.E has no digit input _
6.B has no X in the instruction
7.E enables stack lift, the others disable it
8.D does not affect LASTX
9.D only one argument function
10.D takes no negative arguments

As to which answer is ‘best’, however, that is up for debate!

Cheers, Werner
