B) can be observed in the laboratory, but probably have no biological relevance.

Quizplus · Accepted Answer

Double-stranded regions of RNA can form between two self-complementary regions of the same single strand of RNA. This is known as RNA folding or secondary structure formation, which is important for RNA function in processes such as transcription, translation, and RNA catalysis.
