Mark the correct alternative in each of the following:

If are the position vectors of points A, B, C, D such that no three of them are collinear and then ABCD is a

And,

(Given)

Multiplying the aqbove mentioned equation by ,

So, the position vector of mid – point of BD = Position Vector of mid - point of AC.

Hence the diagonals bisect each other.

Therefore the given figure ABCD is a parallelogram.

Option (D) is the answer
