Which of the following are intermediates in Sandmeyer reaction ?
(i) `C_(6)H_(5)N^(+) -= NCl^(-) ` (ii) `C_(6)H_(5)N^(+) -= N`
`(ii)C_(5)H_(5)` (iv) `C_(6)H_(5)Cl`

Options

A. (ii) and (iii)
B. (ii) and (iv)
C. (i) and (ii)
D. (i) and (iv)

Explanation

To determine which of the given compounds are intermediates in the Sandmeyer reaction, we need to understand the reaction mechanism and the role of intermediates involved.

### Step-by-Step Solution:

1. **Understanding the Sandmeyer Reaction**:
The Sandmeyer reaction involves the conversion of aryl diazonium salts into aryl halides or aryl nitriles using copper salts. The general reaction can be represented as:
- Aryl diazonium chloride (C6H5N2+ Cl-) reacts with CuX (where X is Cl, Br, or CN) to produce aryl halides or nitriles.
