    A A vertical line Correct Answer Incorrect Answer
    B A horizontal line Correct Answer Incorrect Answer
    C A downward sloping straight line Correct Answer Incorrect Answer
    D A concave curve Correct Answer Incorrect Answer

    Solution

    When x is a neutral good, the consumer's utility does not change with the quantity of x. Therefore, the indifference curve will show combinations of x and y that give the same level of utility. Since changes in x do not affect utility, the indifference curve must be horizontal, indicating that utility is determined solely by the quantity of y, regardless of the amount of x.
