### Determine if the Following Vectors are Orthogonal

Given the vectors:

\[ \mathbf{a} = \begin{pmatrix} 6 \\ -5 \end{pmatrix} \]
\[ \mathbf{b} = \begin{pmatrix} -2 \\ -2 \end{pmatrix} \]

#### Select the correct choice below and fill in the answer box to complete your choice. (Type an integer or a simplified fraction.)

- **A.**  The vectors **a** and **b** are orthogonal because \(\mathbf{a} + \mathbf{b} = \) [ \_\_\_\ ] 
- **B.**  The vectors **a** and **b** are not orthogonal because \(\mathbf{a} \cdot \mathbf{b} = \) [ \_\_\_\ ]
- **C.**  The vectors **a** and **b** are not orthogonal because \(\mathbf{a} + \mathbf{b} = \) [ \_\_\_\ ]
- **D.**  The vectors **a** and **b** are orthogonal because \(\mathbf{a} \cdot \mathbf{b} = \) [ \_\_\_\ ]
