Final answer:
The Hydroxypropionate Cycle is found in certain bacteria that are chemoautotrophs, synthesizing sugars by extracting energy from inorganic compounds. The correct option is A.
Step-by-step explanation:
The Hydroxypropionate Cycle occurs in a specific group of organisms known as chemoautotrophs, which includes certain types of bacteria.
These bacteria are capable of synthesizing sugars not by using the energy from sunlight as is the case in photosynthesis, which is performed by plants, algae, and cyanobacteria, but by extracting energy from inorganic chemical compounds.
