Writing a sum$-$of$-$products Boolean equation based on a given truth table requires:

Select one:

a$.$ Locating all outputs that are a logic LOW, writing the minterm for each of these outputs, and ORing them together.

b$.$ Locating all outputs that are a logic LOW, writing the minterm for each of these outputs, and ANDing them together.

c$.$ Locating all outputs that are a logic HIGH, writing the minterm for each of these outputs, and ANDing them together.

d$.$ Locating all outputs that are a logic HIGH, writing the minterm for each of these outputs, and ORing them together.
