Answer:
B
Explanation:
Since p is parallel to q, we know that f & h are equivalent as they're alternate angles. Furthermore, a & b have to be supplementary as they must add up to 180. I'm in calc 2, so I can't remember the theorem, but you can look at this geometrically too. It's a line that's completely horizontal, so it needs to add to 180.
B is out of place here because b is not equivalent to g. b is equivalent to c, and I think we can say those are equivalent to f and h, not e or g.
