Solution
The correct option is B 400-700
Sunlight or solar radiations reaching the earth have wavelength between 300 nm (in the ultra volt rang) to 2600 nm (in the infa-red range). Part of the spectrum used in photosynthesis has a wavelength between 400-700 nm, it is called as photo synthetically active radiation (PAR).
