Which are assemblages of abiotically produced polymers?

A) Ribozymes
B) Stromatolites
C) Protobionts
D) Endosymbionts
E) Polyribosomes

Protobionts

Assemblages of organic polymers that spontaneously form under certain conditions. Protobionts may have been involved in chemical evolution.

Abiotically Produced

Referring to substances or processes occurring without the involvement of biological organisms, typically through physical or chemical phenomena.

Ribozymes

RNA molecules capable of catalyzing specific biochemical reactions, similar to protein enzymes.
