B. Manometer, potometer,porometer, osmometer
C. Porometer, manometer, potometer, osmometer
D. Potometer, porometer,manometer,osmometer.

Answer

To find the correct order for the instruments used for measuring (i) Transpiration, (ii) Size of stomata, (iii) Atmospheric pressure, and (iv) Osmosis, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the instrument for measuring Transpiration**:
- Transpiration is the process of water loss from the aerial parts of the plant. The instrument used to measure transpiration is the **potometer**.

2. **Identify the instrument for measuring Size of Stomata**:
- The size of stomata can be measured using a device called a **porometer**. This instrument assesses the size and density of stomata on plant leaves.

3. **Identify the instrument for measuring Atmospheric Pressure**:
- Atmospheric pressure is measured using a **manometer**. This instrument helps in determining the pressure exerted by the atmosphere.

4. **Identify the instrument for measuring Osmosis**:
- Osmosis, which is the movement of water through a semi-permeable membrane, is measured using an **osmometer**. This device is specifically designed to measure osmotic pressure.

### Final Order of Instruments:
- (i) Transpiration - **Potometer**
- (ii) Size of Stomata - **Porometer**
- (iii) Atmospheric Pressure - **Manometer**
- (iv) Osmosis - **Osmometer**

Thus, the correct order of instruments is:
1. Potometer (Transpiration)
2. Porometer (Size of Stomata)
3. Manometer (Atmospheric Pressure)
4. Osmometer (Osmosis)
