The correct answer is option A
The answer is as following
The new matrix is 2 rows and 2 columns . i.e. it is 2*2 matrix
The element a₁₁ =5*2 + 0*2 = 10
The element a₁₂ = 5*-1 + 0*-2 = -5
The element a₂₁ = 3*2 +-5*2 = -4
The element a₂₂ = 3*-1 + -5*-2 = 7
The new matrix will be
![\left[\begin{array}{ccc}10&-5\\-4&7\end{array}\right]](https://tex.z-dn.net/?f=%20%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D10%26-5%5C%5C-4%267%5Cend%7Barray%7D%5Cright%5D%20)
