Detailed explanation-1: -In addition to the lack of histones, mitochondria and chloroplasts have circular, single stranded DNA. Single stranded, circular DNA is found exclusively in prokaryotes. This evidence supports the endosymbiosis theory because these characteristics would allow the mitochondria and chloroplasts to survive on their own.
Detailed explanation-2: -Mitochondria and chloroplasts likely evolved from engulfed prokaryotes that once lived as independent organisms. At some point, a eukaryotic cell engulfed an aerobic prokaryote, which then formed an endosymbiotic relationship with the host eukaryote, gradually developing into a mitochondrion.
Detailed explanation-3: -> Mitochondria and Chloroplast both have their own DNA and are able to replicate/divide independently of the main cell. This supports the theory that eukaryotic cells engulfed photosynthetic and chemosynthetic prokaryotes at some point in evolution. Option C is the correct answer.
