Let's analyze the given setup step by step:

A white object emits white light, which contains all colors of the visible spectrum.
Y (Yellow filter) allows yellow light to pass through while absorbing other colors.
B (Blue filter) allows blue light to pass through while absorbing other colors.
The eye observes the final light that emerges after passing through both filters.

What Happens to Light?
1 First Filter (Yellow - Y)

The yellow filter transmits yellow light (which is a combination of red and green) and absorbs other colors (including blue).
So, only yellow light moves forward.

2 Second Filter (Blue - B)

The blue filter transmits only blue light and absorbs other colors.
However, yellow light does not contain blue, so the blue filter blocks all the yellow light.

Final Observation
Since the blue filter blocks all the yellow light, no light passes through, meaning the observer sees black (absence of light).

Correct Answer:
E. Black
