The correct answer is (a).
The maxim “SALUS POPULI SUPREMALEX” means “the welfare of the people is the supreme law.” It is a principle of law that states that the government has the power to take actions that are in the best interests of the people, even if those actions violate the rights of individuals.
Section 121 of the Indian Evidence Act, 1872, deals with the admissibility of evidence of public documents. Public documents are documents that are made by a public officer in the course of his or her official duties. Section 121 provides that public documents are admissible in evidence without proof of their authenticity.
The maxim “SALUS POPULI SUPREMALEX” is relevant to Section 121 because it provides the justification for the admissibility of public documents. Public documents are admissible in evidence because they are necessary for the government to be able to carry out its functions in the best interests of the people.
The other options are not relevant to the maxim “SALUS POPULI SUPREMALEX.” Section 122 deals with the admissibility of evidence of private documents. Section 123 deals with the admissibility of evidence of oral statements. Section 124 deals with the admissibility of evidence of opinion.
