Answer:
Prokaryotes lack a true nucleus with well defined nuclear membrane and other membrane-bound organelles. Mitochondria are the double membrane bound organelle and hence is absent in prokaryotes. Mesosome is an extension of the cell membrane presence in the cytoplasm as infolding and serves to increases surface area and as a site for cellular respiration in prokaryotes. Histones are positively charged proteins that serve in the packaging of negatively charged eukaryotic DNA but are absent in prokaryotes.
So, the correct answer is option A.(DNA is complexed with histones).

Explanation:
When sodium chloride is formed from a positively charged sodium atom and a negatively charged chlorine atom, the charge on the salt becomes neutral is true
Explanation
Sodium ion ( positively charged) combine with chloride ion ( negatively charged) to sodium chloride which is neural according to equation below.
Na⁺ + Cl⁻ → NaCl (<em>neutral</em>)
Equal number of positive and negative charges add up to make neutral Nacl therefore the statement above is true.
