The number of different matrices that can be formed with elements 0,1,2 or 3, each matrix having 4 elements, is

- $3×2_{4}$
- $2×4_{4}$
- $3×4_{4}$
- none of these

and in every such matrix,there are four elements each element in the matrix is independent and has 4 different choices

$∴$ The number of different matrices that can be formed =$3×4_{4}$
