We recall that the bisectors are what divides a segment or an angle in half. So, the first blank should be completed with the word: "bisector".
For the second fill-in-the-blank. I have to admit I could pick a number of different answers, since those are what I would use.
But definitely the one with which I would have enough to construct basically anything is that given on answer A:
A protractor, a straightedge, and a pencil.
The other one that comes next, but is not a complete as A is answer D. This is because with a compass you can get some easy angles to be drawn, but not any angle as easily as with a protractor.
