Consider the following Sum of products expression, $$F.$$
$$F = ABC + \overline A \overline B C + A\overline B C + \overline A BC + \overline A \overline B \overline C $$

The equivalent Product of Sums expression is

A
$$F = \left( {A + \overline B + C} \right)\left( {\overline A + B + C} \right)\left( {\overline A + \overline B + C} \right)$$
B
$$F = \left( {A + \overline B + \overline C } \right)\left( {A + B + C} \right)\left( {\overline A + \overline B + \overline C } \right)$$
C
$$F = \left( {\overline A + B + \overline C } \right)\left( {A + \overline B + \overline C } \right)\left( {A + B + C} \right)$$
D
$$F = \left( {\overline A + \overline B + C} \right)\left( {A + B + \overline C } \right)\left( {A + B + C} \right)$$
