The data suggests that ancient eukaryotes lacked a cell wall, which is a characteristic of prokaryotes. They also had a cytoskeleton and a nucleus, which are both characteristics of modern eukaryotes. Therefore, it is reasonable to conclude that the first eukaryote was capable of phagocytosis, a process that involves engulfing and absorbing other organisms or particles, which requires a cytoskeleton and a nucleus. The other choices do not have sufficient evidence to be supported by the data presented.
