Answer 1

D. similar structures in eukaryotes with slight variations depending on their use

Explanation: Endosymbiosis implies a common ancestral origin for key eukaryotic features (e.g., mitochondria, chloroplasts), so descendants share homologous structures that have been modified for different functions.
