Answer 2

Answer;

c.circular; single stranded

Explanation;

Unlike the linear DNA of most eukaryotes, typical bacterial chromosomes are circular. Most bacterial chromosomes contain a circular DNA molecule – there are no free ends to the DNA.

Similarly some viruses contain circular and single stranded DNA.
