As photosynthesis is a process that requires sunlight, the rate of this process will be 0 in a room without any light.
However, even if the dark room has very little light, it may still not be enough for photosynthesis to occur. This process requires certain levels of sunlight.
D acceleration is the answer
There are three types of hazards

- chemical such as cleaner, chlorine (chemical substances)
- biological such as bacteria, mold (live organisms)
Because filet bone is a physical hazard the answer is D (filet bone)
