• B. cylinder
• C. parallelogram
• D. pyramid

Answer 1

The correct option is C parallelogram

$\Rightarrow$ In a given question it is given that ABCD is a quadrilateral.

$\Rightarrow$ We know that quadrilateral has four sides and sum of it's interior angles is 360${}^{\circ }$

$\Rightarrow$ And option A, B and D are not types of quadrilateral because they are not satisfying the properties of quadrilateral.

$\Rightarrow$ Option C parallelogram is a type of quadrilateral having fours sides and sum of its interior angles is 360${}^{\circ }$.

$\Rightarrow$ And its diagonals bisect each other at point O as given in figure.

$\Rightarrow$ So, right option is option C.
