Answer is A: a single, circular DNA molecule.
See proof at this website (definition quoted below).
http://www.ornl.gov/sci/techresources/Human_Genome/glossary/glossary.shtml
"Chromosome
The self-replicating genetic structure of cells containing the cellular DNA that bears in its nucleotide sequence the linear array of genes. In prokaryotes, chromosomal DNA is circular, and the entire genome is carried on one chromosome. Eukaryotic genomes consist of a number of chromosomes whose DNA is associated with different kinds of proteins. "

A(a single circular DNA molecule) is the correct answer.

Alright, I'm not sure about this, but I think it's A. Prokaryotes generally have circular DNA molecules called plasmids. So, A. Maybe.

True ... sort of. Chromosomes are actually composed of Chromatin. Chromatin is both the DNA and associated packing proteins (histones), repair proteins, replication proteins (transcription factors, promoters, repressors, etc.), DNA winding/unwinding proteins (topoisomerases), etc. But if you had a "naked" DNA-only chromosome, you'd still *call* it a chromosome.

B a single linear DNA molecule because it has a set of acid,base,and a sugar
