A Correct answer
Explanation

Life cannot currently originate from inorganic compounds because high oxygen levels oxidize and break down organic molecules before they can form complex life. Early Earth had little oxygen, allowing organic molecules to accumulate. The other options are incorrect - hydrogen is still available, raw materials exist, and temperature is suitable.
