According to De morgan's Theorem States that: (AB)' = A'+B' and (A+B)' = A'B'.
So therefore (ABC)' = A'+B'+C' and (DE)' = D'+E'. So option C is correct.
So therefore (ABC)' = A'+B'+C' and (DE)' = D'+E'. So option C is correct.

As per my knowledge, it is;
((ABC) + (DE))' = (ABC)' (DE)' = (A' + B' + C')(D' + E').
((ABC) + (DE))' = (ABC)' (DE)' = (A' + B' + C')(D' + E').
