The acidic, basic or amphoric nature of `Mn_(2)O_(7), V_(2)O_(5)` and `CrO` are respectively.

Options

A. acidic , acidic and basic
B. basic, amphoteric and acidic
C. acidic , amphoteric and basic
D. acidic, basic and amphoteric

Explanation

To determine the acidic, basic, or amphoteric nature of the oxides Mn₂O₇, V₂O₅, and CrO, we can analyze each oxide based on the oxidation states of the metal and their general properties.

### Step-by-Step Solution:

1. **Identify the Oxidation States**:
- For **Mn₂O₇**: Manganese (Mn) has an oxidation state of +7.
- For **V₂O₅**: Vanadium (V) has an oxidation state of +5.
- For **CrO**: Chromium (Cr) has an oxidation state of +2.
