What will be the `pO_(2) and pCO_(2)` in the atmospheric air compared to those in the alveolar air?
(i) `pO_(2)` lesser, `pCO_(2)` higher
(ii) `pO_(2)` higher, `pCO_(2) lesser
(iii) `pO_(2)` higher, `pCO_(2) higher
(iv) `pO_(2)` lesser, `pCO_(2)` lesser

Explanation

To determine the partial pressures of oxygen (pO₂) and carbon dioxide (pCO₂) in atmospheric air compared to those in alveolar air, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Partial Pressure**:
- Partial pressure refers to the pressure exerted by a single type of gas in a mixture of gases. In this case, we are comparing the partial pressures of oxygen and carbon dioxide in atmospheric air and alveolar air.

2. **Identify the Values**:
