The sum of the eigenvalues of the matrix $$\begin{pmatrix} 5 & 4 \\1 & 2\end{pmatrix}$$ is​

Correct option is B

​$$\text{Given matrix: } A = \begin{pmatrix} 5 & 4 \\ 1 & 2 \end{pmatrix} \\\text{Sum of eigenvalues of a matrix} = \text{Trace of the matrix} \\\text{Trace}(A) = 5 + 2 = 7 \\\therefore \text{Sum of eigenvalues} = 7$$
