Answer:
a. G || h
Step-by-step explanation:
In a plane, you have parallel lines b, f, g, and line h perpendicular to b, and you want to identify the false relationship.
In a plane, lines parallel to the same line are parallel to each other. Here, that means lines b, f, and g are all parallel to each other.
If one of them is perpendicular to line h, then all of those parallel lines are perpendicular to line h. Here, that means line G cannot be parallel to line H, choice A.
