Answer:
D. Midpoint
Step-by-step explanation:
Bisecting means a separation directly in the middle;
A point that bisects a line will be exactly halfway along the line, which is known as the midpoint
Another way of thinking about this is:
A line segment is a kind of line, representing a portion of the line;
A parallel is also a kind of line, one that has the same gradient as another;
The 'C' option is a line itself;
The question is asking for a term that defines a point, hence none of the other 3 terms are valid as answers;
The only option that defines a point is option D
