Correct Answer:

all of the preceeding,F factor,sex factor,episome

Explanation:

A plasmid is an extrachromosomal, extranuclear DNA molecule occurring free in the cytoplasm and capable of autonomous replication (independently of the chromosomalDNA). It usually occurs in bacteria, sometimes in eukaryotic organisms.Some plasmids can become associated with another plasmid or with nuclear chromosome; in the latter case, the plasmid is known as episome. In another words, an episome is a plasmid of bacteria or viral DNA that can integrate itself into the chromosomal DNA of the host organism.F
