Answer and explanation
Correct answer: 3
The roster lists three distinct members: Monday, Tuesday, and Wednesday. The cardinality n(S) is found by counting the members, not by counting all days of the week or assigning numerical values to the names. Since there are exactly three different day names in S, n(S) = 3, so option B is correct.
