Answer 1

c).

Answer 2

If this is Euclidean Geometry, C.

Else: No suitable answer.

Answer 3

Actually, I redact my previous, it is A unless you are taking projected spherical geo. in which case no suitable.

Answer 4

Actually the answer is b)... all of the others are correct, b) is not correct because only one plane is involved in each.

Answer 5

i am for b

Answer 6

its definitely not c

Answer 7

yes - i think b

Answer 8

planes - if you mean a 2d and a 3d thing, then it's b
