Answer: B
Step-by-step explanation:
Transform a matrix by switching the rows and columns:
[tex]A=\left[\begin{array}{cc}a&b\\c&d\end{array}\right] \qquad \rightarrow \qquad A^T=\left[\begin{array}{cc}a&c\\b&d\end{array}\right][/tex]
[tex]N=\left[\begin{array}{cc}7&3\\0&-2\end{array}\right] \qquad \rightarrow \qquad N^T=\left[\begin{array}{cc}7&0\\3&-2 \end{array}\right][/tex]
