Consider

$4-$to$-1$ MUX with

Data inputs: $10,11,12,13$

Control inputs: A$,$ B

Data output: F

Connected to $10$ is a NOR gate with

Data inputs: C$,$ D

Connected to $11$ is an AND gate with

Data inputs: C$,$ D

Connected to $12$ is a $"$O$"$

Connected to $13$ is a $"1"$

Type the resulting Sum of Product $($SOP$)$ from this logic design:
