	A.
	B.
	C.
	D.

 

Answer 1

Multiplication of two matrices is possible if the number of columns in the

first matrix equals the number of rows in the second matrix.

Let A be the first matrix and B be the second matrix.

The dimensions of the first matrix A are 3×2, so the number of the columns

in the first matrix is 2.

The dimensions of the second matrix B are 2×3, so the number of the rows

in the second matrix B is 2.

The number of columns in the first matrix equals the number of rows in the

second matrix. So, matrix product is possible and its dimensions are 3 ×3

Let P be the matrix product.

The product matrix is .

So option B is correct.
