A statement of Assertion (A) is followed by a statement of Reason (R). Estimate the correct option.
 
Assertion (A) :Consider trapezium \( ABCD\) where \( AB\) and \( CD\) are parallel. A line segment \( EF\) is drawn parallel to \(AB\), meeting \( AD\) at \( E\) and \( BC\) at \( F\). Then \(\frac{AE}{ED}=\frac{BF}{FC}\).
 
Reason (R) : Every line parallel to the two parallel sides of a trapezium creates proportional segments on the non-parallel sides.
