Implement the full adder functions using the following PLA.

$s=abc*+a^{\text{'}}bc*+a^{\text{'}}{b}^{\text{'}}r+$abc;

$c=ab+ac$

$s=a{b}^{\text{'}}{c}^{\text{'}}+a^{\text{'}}b{c}^{\text{'}}+a^{\text{'}}bc+a^{\text{'}}{b}^{\text{'}}{c}^{\text{'}}$;

$c-ab+ac$

None of them

$s=a{b}^{\text{'}}{c}^{\text{'}}+a^{\text{'}}b{c}^{\text{'}}+a^{\text{'}}bc+$abc;

$c=ab+bc+ac$

$s-a{b}^{\text{'}}{c}^{\text{'}}+a^{\text{'}}b{c}^{\text{'}}+a^{\text{'}}{b}^{\text{'}}{c}^{\text{'}}+$abc;

$c=ab+bc+ac$
