Question:
Assertion: Every parallelogram is a rectangle.
Reason: The angle bisectors of a parallelogram form a rectangle.
(a) Both Assertion and Reason are true and Reason is a correct explanation of Assertion.
(b) Both Assertion and Reason are true but Reason is not a correct explanation of Assertion.
(c) Assertion is true and Reason is false.
(d) Assertion is false and Reason is true.
Solution:
(d) Assertion is false and Reason is true.
Explanation:
We can easily prove reason (R). So, reason (R) is true.
Clearly, assertion (A) is false (as every parallelogram is not necessarily a rectangle).
Hence, the correct answer is (d).
