The correct response is:

A bacteria cell was engulfed into a host cell through the process of phagocytosis.

This describes the endosymbiotic theory, which posits that mitochondria originated from free-living bacteria that were engulfed by an ancestral eukaryotic cell. Over time, these engulfed bacteria became integral parts of the host cell, evolving into mitochondria.
