Siddharth Laxmisha from The Study Lecole Internationale, PUDUCHERRY

No, Answer D is not correct. They are talking about red, blue, and green lights not red, blue, and green pigments in a leaf. Red and blue lights are efficient in photosynthesizing and the green pigment is also efficient in photosynthesizing. Here, they are talking about lights, not pigments in a leaf.
