    Step-by-step explanation:

    Given

    X = {1,3,5,7}

    Y = {2,4,6,8}.

    Required

    X ∪ Y

    U, in sets is used means union and it means the collection of all sets without repetition.

    So,

    X ∪ Y = {1,3,5,7} U {2,4,6,8}

    Merge sets together

    X ∪ Y = {1,3,5,7,2,4,6,8}

    Arrange elements of the sets in ascending order

    X ∪ Y = {1,2,3,4,5,6,7,8}

    From the list of options, only Set C is equivalent to X U Y;

    Hence, C = X U Y = {1,2,3,4,5,6,7,8}
