In order to find the size of the matrix is given by the product between the number of rows and the number of columns.
Therefore, the size of matrix A is 4x2.
Then, the matrix is arranged as follows
• The first number in a11 represents the row number.
,
• The second number in a11 represents the column number.
So,
The term a11 is 5 because it's positioned at the first row, first column.
The term a32 is 0 because it's positioned at the third row, second column.
The fourth option is correct.
