- C (A) is true but (R) is false
- D (A) is false but (R) is true
Answer & Solution
Correct Answer
(A) (A) is true, (R) is true and (R) is the correct explanation for (A)
Step-by-step Solution
Detailed explanation
Reason (R) \(e^{\operatorname{cosech}^{-1} x}\) is a root of the quadratic equation \(x p^2-2 p-x=0\) We have, \(x p^2-2 p-x=0\)…
