A yellow card will absorb all other colours except yellow and reflect yellow colour. When blue light is incident it simply absorbs it and reflect nothing. This makes it appear BLACK.
Y+B =Black as no colour is common to yellow and blue .Thus all colours are absorbed and the body appears black.The correct option is A (black)
