To accurately choose the best statement that describes the state of a photosynthetic organism at hour 12, we need to consider the typical light cycle. Assuming a standard daily cycle where photosynthesis primarily occurs during daylight:
- a (It is early morning - dimly lit): This would typically occur earlier in the day, before sufficient light is available for photosynthesis.
- b (It is performing the light dependent reactions): This option would be accurate if hour 12 corresponds to a time when sunlight is abundant, typically later in the morning to afternoon.
- c (It is in a drought): This statement doesn't provide information about the light conditions and focuses on water availability.
- d (It is night time - no light): If hour 12 is in a context where it represents the end of the day or night, this would be correct.
Assuming hour 12 is during the day (e.g., mid-day), option b is the best answer, as the organism would be actively performing light-dependent reactions of photosynthesis.
