Final answer:
The correct answers are Osiris as the lord of death, afterlife, and rebirth, and Isis as the mother of Horus and the wife of Osiris. Thus, b) Anubis, Isis is the right choice, recognizing Isis' role as mother and Osiris as ruler of the underworld.
Step-by-step explanation:
Osiris was the lord of death, afterlife, and rebirth while Isis was the mother of Horus and the wife of Osiris and she represented motherhood. Accordingly, the answer to the fill-in-the-blank question is b) Anubis, Isis. This is because Anubis, another prominent Egyptian deity, has close associations with mummification and the afterlife but is not the same as Osiris who is considered the direct ruler of the underworld and seen as a figure of rebirth and resurrection after being brought back to life by his wife, Isis. Ancient Egyptian mythology explains that Osiris was murdered by his brother Seth and was later revived by Isis, who used her magical powers to conceive their son, Horus. Horus went on to avenge his father's death and assume rulership, embodying the living Pharaoh. Isis, revered as a powerful goddess of magic and wisdom, played a crucial role in the Egyptian pantheon and was often depicted as a nurturing mother figure, a depiction that underscores her representation of motherhood.
