Choose the correct statement from among the following

Options

A. A node is a point in space where the wave function (V) has zero amplitude
B. The number of peaks in radial distribution is `n - 1`
C. Radial probability density `pi_(n.1) (r ) = 4 pir^(2)R_(m)^(2)(r )`
D. `v^(2)` represents the atomic orbital

Explanation

To solve the question of choosing the correct statement from the options provided, we will analyze each statement step by step.

### Step 1: Analyze the First Statement
**Statement**: A node is a point in space where the wave function Psi has zero amplitude.

**Analysis**:
- A node is indeed defined as a point where the wave function (Ψ) is zero.
- For example, in the 1s orbital, there are no nodes, while in the 2s orbital, there is one radial node where the wave function is zero.
