Answer:
D:QR+RS=QS
Explanation:
We are given that
If point A, B and C are collinear, B is between A nd C, then AB+BC=AC
Points Q, R and S are collinear and R is between Q and S.
We have to find the conclusion about given statement.
If R lie between Q and R
Then, QR+RS=QS (segment addition property)
Because point Q, R and S are collinear.
Therefore, option D is true.
