The bisector is the line that splits either the angle into half, or the line that splits the line into half.
The answer for (b) is the line shown.
The answer for (c) is the line shown.
By the way, the answer for A should be either 47 or 48 degrees, which is 180 - 133 degrees (your answer). They usually want the acute angle rather than the reflex angle unless stated.
