Given below are two statements
Assertion (A): All Cu (II) halides are known except the iodide
Reason (R): \(\mathrm{Cu}^{2+}\) oxidizes \(\mathrm{I}^{-}\)to \(\mathrm{I}_2\)
The correct answer is
- A Both (A) and (R) are correct and (R) is the correct explanation of \((\mathrm{A})\)
- B Both (A) and (R) are correct and (R) is the correct but \((\mathrm{R})\) is not the correct explanation of \((\mathrm{A})\)
- C (A) is correct but (R) is not correct
- D (A) is not correct but ( \(\mathrm{R})\) is correct
