If B is a proper subset of C, we have
B ⊊ C
This means that B is a any subset of B which is not equal to C. So the maximum number of elements of B is the cardinality of C minus one.
Thus the maximum number of elements of B is 8-1 = 7.
Since the empty set ∅ is a member of every set, the least number of elements of B is 0.
