Explanation / Answer

3. Primary symbiosis, both primary and secondary symbiosis.

Symbiogenesis is a theory expaining the evolution of eukaryotic cells from prokaryotes. According to theory, many organelles of eukaryotes are developed as a result of symbiosis of individual unicellular organelles. Molecular and biochemical evidence proposed that chloroplasts developed from cyanobacteria and mitochondria in eukaryotes was developed from proteobacteria.

As per the given diagram, green algae resulted from primary endosymbiosis, and euglania resulted from both primary and secondary endosymbiosis.
