The correct answer is (d). Sapinda relationship includes relationship by half or uterine blood, adoption, and full blood.
Sapinda relationship is a Hindu concept of kinship that refers to people who are related by blood or adoption. This includes people who are related through the father’s side of the family, the mother’s side of the family, or both. Sapinda relationships are considered to be very important in Hinduism, and there are many rules and regulations governing how people in sapinda relationships should interact with each other.
Half or uterine blood relationships are those that are formed through a common mother but different fathers. For example, a person’s half-sister would be someone who shares the same mother but a different father. Adoption relationships are those that are formed when a person is taken in by a family and raised as one of their own. Full blood relationships are those that are formed through a common mother and father.
All of these types of relationships are considered to be sapinda relationships in Hinduism.
