The logic expression for the output of the circuit shown in figure below is:

1. $\overline{AC} + \overline{BC} +CD$

2. $A\overline{C} + B\overline{C} + CD$

3. $ABC +\overline {C}\; \overline{D}$

4. $\overline{A}\; \overline{B} + \overline{B}\; \overline{C} +CD$

Anyone with A'C + B'C + CD?

NO option match

Better to simplify the circuit:

yeah NAND-NAND Realization is Nothing but AND-OR  Realization

(((AB)' C)' (CD)' )' = ((AB)'C) + CD) = (A' + B')C + CD = A'C + B'C + CD
