    Solution:

    Concept- Only when the red and green colours are combined does the yellow colour appear, and we must now obtain the two-colour combination on the eye retina in order to see the yellow colour. Unless we get the right colour combination through the filter, we won't be able to see the yellow colour.
    All colours except the one intended for it are absorbed by a filter. The colours red and green make up yellow light. When a dress reflects red and green light, it appears yellow to our eyes. In order for red and green light to be reflected, these two primary colours of light must be present in the incident light. As a result, the blue-colored filter only allows blue to pass through while absorbing all other colours. The yellow dress appears black as a result.
    Hence, option 4 is the correct answer.
