Matrix is an arranged array of rows and columns. The number of rows are represented by m and number of columns by n. Hence the elements of matrix is denoted by small letter with it's row number and column number in subscript.

Like elements belonging to A matrix will be written as:

In the given matrix, we have to tell the element b_23 which means we have to point out the element in row 2 and column 3.

Looking at the matric we can see that the number at the position of 2nd row and third column is 9.

Hence Option C is the correct answer ..
