MCQ
Assertion (A): If we add two monomials, we always get a binomial as the sum.
Reason (R): A monomial has only one term while a binomial has two terms.
  • A
    Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).
  • B
    Both Assertion (A) and Reason (R) are true and Reason (R) is not the correct explanation of Assertion (A).
  • C
    Assertion (A) is true but Reason (R) is false.
  • ✓
    Assertion (A) is false but Reason (R) is true.
✓

Answer

Correct option: D.
Assertion (A) is false but Reason (R) is true.
(D) Assertion (A) is false but Reason (R) is true.
If we add two monomials with like terms, we get a monomial as the sum,
e.g. $3 x^2 y+5 x^2 y=8 x^2 y$.
So, $A$ is false.
