Answer:
N K Q
Step-by-step explanation:
The element on the position (1,1) in the product matrix FC is a scalar product of the first row in F and the first column in C.
Therefore the element in the position (1,1) in FC will be a scalar product of (-2,0) and (12,1):

The only matrix that has a value of -24 in the position (1,1) is matrix B.
Therefore, the answer is matrix B.
