    Yes, you are correct. D should be a correct option because protobionts were partially isolated from environment, but, they could not separate combinations of molecules from the surroundings. protobionts exhibit some of the properties associated with life, including reproduction and metabolism, and can maintain an internal chemical environment different from their surroundings. Lab experiments show the spontaneous formation of protobionts from abiotically produced organic compounds.

    sir, can probionts reproduce?.

    Sajan sarthak best-answer

    As they are surrounded by a membrane their internal and external part is completely isolated also they are able to reproduce

    eduncle-logo-app

    means they can reproduce? then option B will be wrong.
