B. carrying information for making proteins

C.replicating or making copies of itself

Answer 1

Answer:

The correct option is A)  carrying genetic information

Explanation:

In the 1960s, a hypothesis was brought forward that initially, RNA was the material for storing and carrying the genetic information. The hypothesis suggested that with the passage of time as DNA became the genetic material as RNA itself was an unstable molecule. The scientists thought that around 400 billion years ago, RNA was the only living substance which functioned both as genes and enzymes. Another property of RNA which supported this hypothesis was the ability of RNA to self replicate.
