A statement of Assertion (A) is followed by a statement of Reason (R). Estimate the correct option.
Assertion (A) :In trapezium
\(ABCD\) with
\(
AB∥CD\), points
\(
E\) and
\(
F\) are chosen on
\(
AD\) and
\(
BC\) respectively so that
\(
AB∥DC\). Then \frac{AE}{ED}=\frac{BF}{FC}\).
Reason (R) : Any line parallel to parallel sides of a trapezium divides the non-parallel sides proportionally.
