Answer:

B

Explanation:

the order of a matrix are given as

m × n ( m is the number of rows and n the number of columns

matrix A is of order 2 × 3

matrix B is of order 3 × 2

for the matrices to be conformable for multiplication then

the number of columns in A is equal to the number of rows in B

This is the case here , then the order of the resulting product is

AB : 2 × 3 × 3 × 2 the outer values , that is 2 × 2
