Solution

The correct option is A If both the assertion and the reason are true and the reason is a correct explanation of the assertion
Prokaryotic chromosome (prochromosome) consists of a naked double strand of DNA, that is the DNA is not associated with histone proteins. DNA is not linear but is circular with no free ends. DNAs of mitochondria and chloroplast resembles prokaryotic chromosome and are, therefore, called organelle prochromosome.
