Question 431 Mark
Directions: In the following questions, the Assertions (A) and Reason(s) (R) have been put forward. Read both the statements carefully and choose the correct alternative from the following:
Assertion: Degree of a zero polynomial is not defined.
Reason: Degree of a non-zero constant polynomial is 0.
  1. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
  2. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
  3. Assertion is correct but Reason is incorrect.
  4. Assertion is incorrect but Reason is correct.
Answer
  1. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
    Solution:
    We know that,
    The constant polynomial 0 is called a zero polynomial.
    The degree of a zero polynomial is not defined.
    $\therefore$ Assertion is true.
    The degree of a non-zero constant polynomial is zero.
    $\therefore$ Reason is true.
    Since both Assertion and Reason are true and Reason is not a correct explanation of Assertion.
