Final Answer :
C
Explanation :
It is unlikely that the earliest cells were aerobic, as aerobic respiration requires oxygen, which was not abundant in the early atmosphere. The other four characteristics, prokaryotic structure, autotrophic or heterotrophic metabolism, and anaerobic respiration are all possible traits of the earliest cells.
