Explanation:

The endosymbiotic theory describes how prokaryotic organisms were engulfed by larger cells and became organelles like mitochondria and chloroplasts, which is consistent with the description in the question about an ancient archaeal cell engulfing a prokaryote and it becoming a mitochondria - like organelle. The theory of natural selection is about the survival and reproduction of the fittest. The theory of Lamarckian inheritance is about acquired characteristics being passed on. The theory of genetic drift is about random changes in allele frequencies in a population.

Answer:

Theory of Endosymbiotic theory
