Solution
The correct option is B PAR
Visible light ranges from low blue to far-red light and is described as the
wavelengths between 380 nm and 750 nm, although this varies between individuals.
The region between 400 nm and 700 nm is what plants use to drive photosynthesis
and is typically referred to as photosynthetically active radiation (PAR). Plants use wavelengths
outside of PAR for the phenomenon known as photomorphogenesis, which is light
regulated changes in development, morphology, biochemistry and cell structure and
functionSo, the correct answer is 'PAR'
