Answer:
The correct option is 1.
Explanation:
From the given figure it is clear that QT=32, TR=36, QU=40 and US=45.
The converse of side splitter theorem states that if a line divides two sides proportionally, then that line is parallel to the third side.
The ratio in which TU divides the two sides is



It means the line TU divides two sides proportionally.
Using converse of side splitter theorem, Line segment TU is parallel to line segment RS because

Therefore the correct option is 1.
