Answer:
5) mitochondria and chloroplasts
Explanation:
The theory of endosymbiosis was proposed by Lynn Margulis in 1967 which stated that the life the energy-producing organelles called chloroplast and mitochondria evolved when the smaller bacteria were engulfed by the larger prokaryotes.
When the photosynthetic bacteria were engulfed by the bacteria then the bacteria formed a symbiotic relationship with the larger prokaryote and now is known as chloroplast whereas when chemical using bacteria was engulfed by the prokaryote it formed the mitochondria.
Thus, 5) mitochondria and chloroplasts is the correct answer
