List of top Computer Awareness Questions on Boolean Algebra

If \( x \) and \( y \) are Boolean variables, then which of the following statement is/are incorrect?
a. \( x \lor 0 = x, \, x \land 1 = x \)
b. \( x \lor x' = 1, \, x \land x' = 0 \)
c. \( x \land (x \lor y) = x \)
d. \( x \land (x \land y) = x \lor y \)
The dual of \( x \lor (y \land 0) \) is
