If `A` and `B` are two sets, then `A nn (A uu B)'` is equal to -

A

`A`

B

`B`

C

`phi`

D

`A nn B``

Text Solution

Verified by Experts

The correct Answer is:
C
`X nn (X uu Y)' = X nn (X' nn Y') , [:' (A uu B)' = A' nn B']`
`= (X nn X') nn (X nn Y')`
`= phi nn (X nn Y') = phi , [:' phi nn A = phi]`
