The correct answer is option D, "The pigment chlorophyll reflects green light waves"
The chloroplast with in the plants consists of chlorophyll (green colour pigment) which is highly absorbent to the long and short wavelengths such as red and blue wavelength of visible spectrum and reflects green wavelengths thereby producing green colour visualizations to the viewer. The two common chlorophyll usually found in the leaves are chlorophyll A and B. Chlorophyll A is majorly responsible for reflecting the green light
Answer:

°
Explanation:
Let's use the component method of vector addition:

Now, we know:

So:

Now lets calculate the magnitude of the vector B:

Finally its angle is given by:
°
Keep in mind that I added 180 to the angles of C and B to find the real angles measured from the + x axis counter-clock wise.
