B. 6928
C. 6908
D. None of these

Answer

To solve the equation \( 209 \times 33 + 21 = ? \), we will follow the order of operations, which is to perform multiplication before addition.

### Step-by-step Solution:

1. **Multiply 209 by 33**:
\[ 209 \times 33 \]
- To calculate this, we can break it down:
\[ 209 \times 33 = 209 \times (30 + 3) = 209 \times 30 + 209 \times 3 \]
- Calculate \( 209 \times 30 \):
\[ 209 \times 30 = 6270 \]
- Calculate \( 209 \times 3 \):
\[ 209 \times 3 = 627 \]
- Now add these two results together:
\[ 6270 + 627 = 6897 \]

2. **Add 21 to the result of the multiplication**:
\[ 6897 + 21 \]
- Perform the addition:
\[ 6897 + 21 = 6918 \]

3. **Final Result**:
\[ 209 \times 33 + 21 = 6918 \]

### Conclusion:
The answer to the equation \( 209 \times 33 + 21 = ? \) is \( 6918 \).
