The correct answer is letter C
Marriage is the voluntary union between two people who wish to start a family, forming a conjugal bond that is based on the conditions provided by civil law.
The so-called "civil marriage" is the act of uniting two people under civil law. In this case, in some countries, for example, the civil union may consist of people of both sexes.
But, in the religious sphere, marriage is an act exclusively intended for heterosexual couples (a man and a woman), this condition being described in the Christian holy bible.
