Answer:
It can be seen that A⊂{0,1,2,3,4,5,6}
B⊂{0,1,2,3,4,5,6}
However, C⊂{0,1,2,3,4,5,6}
Therefore, the set {0,1,2,3,4,5,6} cannot be the universal set for the sets A, B and C.
(ii) A⊂ϕ,B⊂ϕ,C⊂ϕ
Therefore, ϕ cannot be the universal set for the sets A, B, and C.
(iii) A⊂{0,1,2,3,4,5,6,7,8,9,10}
B⊂{0,1,2,3,4,5,6,7,8,9,10}
C⊂{0,1,2,3,4,5,6,7,8,9,10}
Therefore, the set {0,1,2,3,4,5,6,7,8,9,10} is the universal set for the sets A, B and C.
(iv) A⊂{1,2,3,4,5,6,7,8}
B⊂{1,2,3,4,5,6,7,8}
However, C⊂{1,2,3,4,5,6,7,8}
Therefore, the set {1,2,3,4,5,6,7,8} cannot be the universal set for the sets A, B, and C.
