The multiplication of the matrix will be calculated as:-

M = $\dfrac{1}{2}\left[\begin{array}{cc}12&64&\\78&30&\\\end{array}\right]$

M = $\left[\begin{array}{cc}\dfrac{12}{2}&\dfrac{64}{2}&\\\dfrac{78}{2}&\dfrac{30}{2}&\\\end{array}\right]$

M = $\left[\begin{array}{cc}8&32\\39&15&\\\end{array}\right]$ .

Therefore the correct answer is option C which is $\left[\begin{array}{cc}8&32\\39&15&\\\end{array}\right]$ .
