A, chloroplast and cell wall.
This is because chloroplasts are what plant cells use to do the process of photosynthesis, which animals do not need. Plant cells also have cell walls.
Adaptation, in another words ‘survival of the fittest’
Ribozymes are biochemically too complex to have ever produced themselves naturalistically. They are an intermediate cellular functioning assembly that cannot survive on its own and they are too restrictive in function to enable metabolism and reproduction at the level of criticality to be considered plausible for life.
Their simplicity relative to RNA and DNA make them an attractive possibility, but they are not strategic enough, robust enough or in any producible using naturalistic processes.
