Answer: I only

Step-by-step explanation:

matrix A is 2x2

matrix B is 2x1

matrix c is 1x2

Matrices can only be multiplied if the number of column of first matrix is equal to number of rows in the second matrix. th eresulting matrix size will have same number or rows as the first matrix and same number of columns as the second matrix.

for ex:

let matrix P be axb and Q be cxd

then,

PxQ is possible only if b=c and the size of matrix PxQ will be axd
