does this work?
fizzysoda's said Q10 is B but mok's original version of his solutions said C so which is it?



Then you can check that A,B,C lie on a sphere centre the origin with radius 2 and satisfy the dot products in the question.

Hence fizzysoda's is the correct answer.

EDIT: Mok updated his solutions and the new version now says B too
