To determine the measurement shown on the vernier caliper, we need to add the main scale reading and the vernier scale reading. Here's the step-by-step process:

1. **Main Scale Reading**: The main scale shows a reading between 2.2 cm and 2.3 cm. It is closer to 2.2 cm, so the main scale reading is **2.2 cm**.

2. **Vernier Scale Reading**: To determine this, we find the line on the vernier scale that aligns exactly with any line on the main scale. In the image, the 5th line on the vernier scale aligns perfectly with a line on the main scale.

   The value of the vernier scale reading is calculated as:
   \[
   \text{Vernier Reading} = 5 \times 0.005 \, \text{cm} = 0.025 \, \text{cm}
   \]

3. **Total Measurement**: The total measurement is the sum of the main scale and vernier scale readings:
   \[
   \text{Total} = 2.2 \, \text{cm} + 0.055 \, \text{cm} = 2.255 \, \text{cm}
   \]

Therefore, the correct answer is:
- **B) 2.2550 cm**
