Explanation:

Correct option 3: Parliament and if no parliament is there then from supreme authority

Acts of third person: This option suggests that legal duties and rights come from the actions of other individuals. While third-party acts can influence rights and duties, they are not the primary source.

Society as a whole: Society influences norms and social duties, but legal duties and rights are formally established through legal systems.

Parliament and if no parliament is there from supreme authority: Parliaments and supreme authorities create laws that assign rights and duties, so this is a strong candidate.

Sovereign: The sovereign, or the ultimate legal authority, is traditionally the source of legal powers within a state.
