<h3>Answer:  D) 7</h3>

===================================================

Explanation:

a31 means "the value in the third row, first column". That value is 7

As another example, a22 = 3 since 3 is in the second row, second column.

Another example: a12 = -1 because we're in the first row and second column.

This is a 3x2 matrix due to it having 3 rows and 2 columns.
