Final answer:
Pathicism relates to the passive role in male-male relationships in Roman times and is not associated with any long-term relationship types mentioned in the options. Polygamy involves marriage with multiple spouses, including polygyny and polyandry, while same-sex marriage refers to the union of two adults of the same sex.
Step-by-step explanation:
In terms of long-term relationships, pathicism does not correspond to any of the provided answers (A, B, C, or D). Instead, pathicism refers to the passive partners in male-male sexual relationships during the Roman times. The term is derived from the Latin 'pathicus' with its origins in the Greek language. In Roman sexuality, there was a dichotomy between the penetrator and the passive partner, with the passive ones often being scorned in literature and facing social as well as legal discrimination.
In contemporary society, polygamy refers to the practice of a marriage involving more than two spouses. This practice comes in different forms, including polygyny (one man with multiple wives) and polyandry (one woman with multiple husbands), and its practice can signal status or respond to demographic needs. Same-sex relationships, on the other hand, have gained increasing recognition and support globally, with same-sex marriage legalized in various countries, providing social sanction to unions between two adults of the same sex.
