Answer:

C

Explanation:

#This a multiplication of a vector by a scalar quantity, a 1D product:


=4\left[\begin{array}{ccc}-2&5&0\\1&8&-1\end{array}\right] \\\\\\=\left[\begin{array}{ccc}-8&20&0\\4&32&-4\end{array}\right]

Hence the product of this matrix by a scalar quantity is(the correct answer being C):


\left[\begin{array}{ccc}-8&20&0\\4&32&-4\end{array}\right]
