Question
Consists of two statements, namely, Assertion (A) and Reason (R). For selecting the correct answer, use the following code:
  1. Both Assertion (A) and Reason (R) are true and Reason (R) is a correct explanation of Assertion (A).
  2. Both Assertion (A) and Reason (R) are true but Reason is not a correct explanation of Assertion (A).
  3. Assertion (A) is true and Reason (R) is false.
  4. Assertion (A) is false and Reason (R) is true.
Assertion (A)Reason (R)
e is an irrational number.$\pi$ is an irrational number.
The correct answer is: (a), (b), (c), (d).

Answer

  1. Both Assertion (A) and Reason (R) are true but Reason is not a correct explanation of Assertion (A).
    Solution:
    e and $\pi$ both are irratinoal numbers
    So, both Assertion (A) and Reason (R) are true
    But the Reason (R) is not a correct explanation of Assertion (A), so (b) holds.
