The following correctly represents De Morgan's first law?

(AUB)' = A'∩B'

(A∩B)' = A'UB'

(AUB) = A∩B

None of these

De Morgan's first law states that the complement of the union of two sets A and B is equal to the intersection of their complements.

The correct representation is:

(AUB)' = A' ∩ B'
