The answer is b.
They could maintain an internal environment
Homoeostasis is keeping the internal environment of the body constant. It is necessary for normal life processes. Microspheres are molecular aggregates of proteinoids. Oparin and Sydney Fox held that large organic molecules synthesized abiotically on primitive earth formed large colloidal aggregates due to the intermolecular attraction. These colloidal particles were called coacervates. Oparin called giant nucleoprotein poid molecules as protobionts. These reproduce either by budding a binary fission but do not exhibit homoeostasis.

Which one of the following is incorrect about the characteristics of p...
Characteristics of Protobionts:
• Partially isolated from the surrounding
• Able to maintain an internal environment
• Able to reproduce
Explanation:
Protobionts are believed to be the first step in the abiogenic origin of life. Coacervates and microspheres are the two types of protobionts that have been proposed. They have the following characteristics:
Partially isolated from the surrounding:
Protobionts were partially isolated from the surrounding environment. They had a lipid membrane or a protein coat that separated them from the external environment.
Able to maintain an internal environment:
Protobionts were able to maintain an internal environment that was different from the external environment. They could regulate their internal environment by controlling the exchange of molecules with the external environment.
Able to reproduce:
Protobionts were able to reproduce by either fission or budding. Fission is the process by which a protobiont divides into two daughter protobionts. Budding is the process by which a protobiont produces a small bud that eventually grows into a new protobiont.
Incorrect characteristic:
The incorrect characteristic about protobionts is that they could separate combinations of molecules from the surroundings. While protobionts were able to partially isolate themselves from the surrounding environment, they could not separate specific combinations of molecules from the external environment. Rather, they were able to control the exchange of molecules with the external environment.
