OB = 5, this can be any point with a length of 5 from point O. - Insufficent.

B(3,4) = Clearly sufficient to get the points of A and C, thus perimeter can be found. - Sufficient

Option B

==> If you modify the original condition and the question, the quadrilateral ABCD is a rectangle, so in order to find the perimeter, you only need to know B, hence con 2) is sufficient.

Therefore, the answer is B.
Answer: B

Why is not A sufficient?. Given B is a point and O the origin will the diagonal length not be 5? And can't we calculate the sides of the rectangle from the diagonal? Can someone pls explain.

You can not find the area of a rectangle just knowing the length of its diagonal. Area of a rectangle is length*width and knowing the length of diagonal is not enough to calculate these values. In other words knowing the length of hypotenuse (diagonal) in a right triangle (created by length and width), is not enough to find the legs of it (length and width).
