    Answer:

    Answer:

    (a) 15

    Step-by-step explanation:

    Given sets,

    A = {1, 2, 3, 4, 5},

    B = {6, 7, 8},

    Since, cardinality of a set is the number of elements in the set.

    Also, if the cardinality of a set X is m and cardinality of set Y is n,

    Then the cardinality of set X × Y = m × n

    Here, cardinality of A = 5,

    cardinality of B = 3

    Hence, cardinality of A × B = 5 × 3 = 15

    i.e. OPTION (a) is correct.
