    D)
    Team X Team Y
    White shirts black shorts White shirts, blue shorts

    Correct Answer: C

    Solution :

    The white shirts of team X will appear yellow, because white colour cannot absorb any light and black shorts will appear black because it absorbs yellow colour. The yellow shirts of team Y will appear yellow, because yellow pigment will reflect as yellow light. The blue shorts will appear black, because blue pigment absorbs yellow colour. Thus, the dresses of both the teams appear as yellow shirts and black shorts.
