MCQ
Assertion and Reason Type $\text{MCQ}$
Assertion : Every parallelogram is a rectangle.
Reason : The angle bisectors of a parallelogram form a rectangle.
  • A
    Both Assertion $(A)$ and Reason $(R)$ are true and Reason is a correct explanation of Assertion $(A).$
  • B
    Both Assertion $(A)$ and Reason $(R)$ are true but Reason is not a correct explanation of Assertio $(A).$
  • C
    Assertion $(A)$ is true and Reason $(R)$ is false.
  • ✓
    Assertion $(A)$ is false and Reason $(R)$ is true.
✓

Answer

Correct option: D.
Assertion $(A)$ is false and Reason $(R)$ is true.
Every parallelogram need not be rectangle, since a parallelogram could be a square, or a rhombus too.
So, the Assertion $(A)$ is false.
The angle bi sectors of a parallelogram form a rectangle.
So, the Reason $(R)$ is true.
