- D (d)
Answer & Solution
Correct Answer
(C) (c)
Step-by-step Solution
Detailed explanation
(A) Let \(h=\frac{P}{2}\left(t+\frac{1}{t}\right), k=\frac{q}{2}\left(t-\frac{1}{t}\right)\) \(\Rightarrow \quad \frac{2 h}{p}=t+\frac{1}{t}\) and \(\frac{2 k}{q}=t-\frac{1}{t}\) \(\Rightarrow \quad \frac{4 h^2}{p^2}=t^2+\frac{1}{t^2}+2=\left(t-\frac{1}{t}\right)^2+4\)…
