Answers and Explanations:
1. Criminal Law; the given definition is broad and it mentions "violations of public order or security", so we can infer it has something to do with law of some sort, eliminate A and C. Between civil law and criminal law, civil law is more related to individuals, instead of society or the "public", so eliminate B. Thus, the answer is D.
2. Misdemeanors & felonies; within criminal law are two broad classes of crimes. They are commonly known as misdemeanors and felonies. "Civil" has nothing to do with criminal law (as it is talking about here), and "criminal" is too broad; we're looking for subcategories. So, the answer is A.
3. Civil; as mentioned above, civil law deals with the "relations between individuals", as opposed to criminal law. So, it's not B. "Maritime" is related to the sea and nautical legislations, and "litigation" is not a specific type of law. Eliminate C and D.
Hope this helps!
