Answer:

Option A. (-1)

Step-by-step explanation:

We should always remember an element of a matrix is always represented in (row.column) form.

It means when we have to show an element a_{12} , it means the given element is located in the matrix at first row and second column.

Now we come to the question the given element b_{31} is located in 3rd row and 1st column of the matrix.

Here b_{31}=(-1)

Therefore answer will be (-1) Option A.

An element of a matrix is found by looking at "A(row,column). So in our case, we are looking for b31 where 3 is the row and 1 is the column.

We see that in the third row, first column, the element is -1.
