<h2>b) option is correct </h2>
Explanation:
- Archaea are the closest modern relatives of Earth's first living cells
- Archaea are famous because of living in extreme environments
- If it’s super hot (more than 100° Celsius), freezing, acidic, alkaline, salty, deep in the ocean, even bombarded by gamma or UV radiation, there’s probably life there, and that life is probably archaeal species
- They’re also considered very resourceful
- Many forms of archaea can utilize totally inorganic forms of matter—hydrogen, carbon dioxide or ammonia for example—to generate organic matter themselves
The answer is a (4) I hope this helps out a bit
