MCQ
Assertion (A): There are three rational numbers which are their own reciprocals namely $-1,0$ and 1.
Reason (R): $\frac{b}{a}$ is called the reciprocal of $\frac{a}{b}$.
  • 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.
-1 and 1 are their own reciprocals, but reciprocal of 0 is not defined. So, A is false.
Clearly, R is true.
