Hint: DNA, is the hereditary material in humans and almost all other organisms. Every cell in one's body has the same DNA. DNA informs the cells about what proteins to make. This is common in animals ,plants, protists, animals and bacteria.

Complete answer:
Mitochondrial DNA located in the mitochondria, cellular organelles within eukaryotic cells that convert chemical energy from food. Into a form that cells can use, that is adenosine triphosphate. T nucleus DNA is normally found as a loosely contained structure called chromatin. Within the nucleus.
Nuclear DNAMitochondrial DNA
Nuclear DNA is enveloped by a nuclear membrane.Mitochondrial DNA is not enveloped by any membrane
Nuclear DNA codes for all the proteins required for its functionsMitochondrial DNA is a semi-autonomous organelles.
Nuclear DNA has tight binding of histonesMitochondrial DNA do not possess any such binding
Nuclear DNA is arranged into several chromosomes.Mitochondrial DNA is arranged into a single chromosome
Nuclear DNA contains noncoding regions of DNA like introns and and untranslated regionsMitochondrial DNA lacks noncoding DNA regions like introns.
Nuclear DNA is inherited equally from both parents.Mitochondrial DNA is maternally inherited maternally.

Hence, the correct answer is option (C).
Note: DNA is hereditary material in all the living organisms. Nuclear DNA has a tight binding of histones, and is enveloped by a nuclear membrane. Mitochondrial DNA does not possess such binding and is not enveloped by any such membrane.
