Correct option is A)

From the figure, it is clear that ABCD is a trapezium, because slopes of $BC$ and $AD$ are same.

Now, by distance formula,

$AB=(3−0)_{2}+(2−1)_{2} =10 $

And $CD=(3−0)_{2}+(5−6)_{2} =10 $

$∵AB=BC$, $ABCD$ is an isosceles trapezium.

So, $∠A$ and $∠D$ are equal.

Therefore, $△EAD$ and $△EBC$ are isosceles .

$∴EA=ED$ and $EB=EC$

$⇒EA×EB=ED×EC$.

Which satisfies condition of points lying on circle.

Therefore, A, B, C and D are concyclic.

Hence, both the statements are correct and reason is correct explanation of assertion.
