Correct option(c) a single double stranded DNA
Explanation:
In bacteria nucleoid or genophore is haploid and consists of single, *****, double stranded, circular ring like highly focused supercoiled DNA with no free ends, no histone proteins. The nucleoli of E. coli has a central core of RNA surrounded by about 50 super coolings of DNA which are [hen associated with some basic proteins but never histones. Some proteins like polyamines rich in alanine are also found associated with DNA.
