A) They only replicate the same time as the larger chromosome.

Explanation:

Plasmids are small, circular, double stranded DNA molecule, which can replicate independently from its chromosomal DNA. If plasmids are used for experiments, they are called vectors. Scientists use plasmids as tools for cloning, transferring and manipulating genes. They are distinct from chromosomes in being non-essential. Plasmids are sometimes present in archaea and eukaryotic organisms. Plasmids often carry genes that benefit the survival of the organism, such as by providing antibiotic resistance. They do not replicate the same time as the larger chromosome.
