    Contrapositive are the statements in which we switch the hypothesis and the conclusion of the statement and then we take the negation of both.

    Here the hypothesis is " A line is horizontal"

    And the conclusion is " slope equal to zero"

    In order to make the contrapositive statement we switch the hypothesis and conclusion and then take negation.

    Therefore, the contrapositive statement is given by

    If a line does not have zero slope, then it is not a horizontal line.

    Last option is correct.
