Why is DNase preferred over restriction endonuclease in some cases?

• A. DNase is preferred over restriction endonuclease in some cases because the latter are not able to recognize some of the restriction sites
• B. DNase is more specific as restriction endonuclease, so the required fragment is obtained
• C. DNase is less specific as compared to restriction endonuclease, hence there are more chances of representation of all the possible fragments
• D. DNase is abundant in comparison the restriction endonuclease
