If A, B and C are three sets such that `AnnB""=""AnnC` and `AuuB""=""AuuC` , then (1) `A""=""B` (2) `A""=""C` (3) `B""=""C` (4) `AnnB""=varphi`

A

`AnnB=phi`

B

A = B

C

A = C

D

B = C

Text Solution

Verified by Experts

The correct Answer is:
D
`becauseAnnB=AnnCimpliesB=CandAuuB=AuuCimpliesB=C`
Hence, B = C
