    Answer:

    Option A, They have enzymatic properties that can covalently modify DNA.

    Explanation:

    Histones have very basic nature and possess no enzymatic properties. However, any modification of DNA is carried out after the end of translation process with the help of enzymes on the N –terminal tails through processes such methylation, acetylation, citrullination, phosphorylation.  

    There are several Histone-modifying enzymes in the human genome that interact with the non-histone proteins to form functional complexes

    Hence, option A is correct
