In which light Photosynthesis takes place faster?

Option B

As far as the rate of photosynthesis is concerned, it is fastest in white light making the rate of photosynthesis maximum. white color suits the best as it produces both red and blue color whichever color (that is red and blue color) chlorophyll may need to absorb, its present in white color.

After White, We Have Violet Light Where Photosynthesis Occur To A Higher Extent as It Has The Shortest Wavelength Hence Has The Max Energy.

So The Order Is  ::  white>violet>blue.
