Subset: A subset is a set of which all the element are contained or can be find in the universal set.
From the question above,
ÎĽ = {1,2,4,5,6}
* The first option {0,1,2} is wrong because  0 is not contained in the universal set.
* The second option {3,4} is wrong because, 3 is not contained in the universal set.
* The third option {5,6,7} is wrong because 7 is not contained in the universal set.
* The last option {2,6} is correct because all of the element of the set are contained in the universal set, and as such makes it a subset.
Hence the subset of {1,2,4,5,6} is {2, 6}
