According to Justice Kennedy’s first paragraph, what does liberty have to do with a person’s right to marry whomever they choose?

A  Because the right to privacy is not mentioned in the Constitution, personal liberty does not involve the state-sanctioned institution of marriage.

B  The petitioners in the case seek to exercise their constitutional right to religious liberty by protecting marriage as an institution involving one man and one woman.

C  The petitioners in the case seek to exercise their constitutional liberty by marrying someone of the same sex and having that marriage recognized as equal to heterosexual marriage.

D  Because the constitutional right to privacy has traditionally been interpreted to apply to reproductive issues, liberty in this case can be invoked only by heterosexual couples.
