Choose the correct statement(s) about buffer capacity during titration of `NH_(4)OH` with `HCl`:

Options

A. Buffer capacity during titration first increases then decreases
B. Buffer capacity reaches to maximum at equivalence point.
C. Buffer capacity will increase if concentration of `NH_(4)OH` increases.
D. Buffer capacity value will remain same if strong acid `HCl` is replace by `H_(2)SO_(4)` of equal `[H_(2)O]`

Explanation

To solve the question regarding buffer capacity during the titration of NH₄OH (ammonium hydroxide) with HCl (hydrochloric acid), we can follow these steps:

### Step 1: Understand the Components
- **NH₄OH** is a weak base.
- **HCl** is a strong acid.
- During the titration, NH₄OH will react with HCl to form NH₄Cl (ammonium chloride) and water.

### Step 2: Reaction Equation
