Answer

To solve the problem of converting 2 kg 56 g into kilograms, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Conversion**:
We know that 1 kilogram (kg) is equal to 1000 grams (g). Therefore, to convert grams to kilograms, we can use the formula:
\[ \text{grams} \div 1000 = \text{kilograms} \]

2. **Convert 56 grams to kilograms**:
Using the conversion formula, we convert 56 grams to kilograms:
\[ 56 \, \text{g} = \frac{56}{1000} \, \text{kg} = 0.056 \, \text{kg} \]

3. **Add the kilograms**:
Now we need to add the kilograms from the original measurement (2 kg) to the converted grams (0.056 kg):
\[ 2 \, \text{kg} + 0.056 \, \text{kg} = 2.056 \, \text{kg} \]

4. **Choose the Correct Option**:
Now that we have converted 2 kg 56 g into kilograms, we compare our result (2.056 kg) with the options provided:
- Option A: 2.56 kg
- Option B: 2.056 kg
- Option C: 2.560 kg
- Option D: None of these

The correct answer is **Option B: 2.056 kg**.

### Final Answer:
The correct answer is **2.056 kg** (Option B).
