Which is used as evidence for the idea that the domain eukarya evolved from unicellular organisms? a. organisms in the domain eukarya reproduce sexually. b. eukaryotes are unicellular organisms. c. mitochondria and chloroplasts have their own dna. d. eukaryotes hold genetic information in dna.

The domain Eukarya evolved from the unicellular organisms, and the proof of this can be derived from the endosymbiotic theory. According to this theory, the organelles, such as mitochondria and chloroplasts were previously free-living organisms. This is supported by the fact that the mitochondria and chloroplasts have their own DNA (deoxyribonucleic acid).

Hence, the answer is 'Option C - mitochondria and chloroplasts have their DNA.'

c
