Anubis opened the mummies’ mouths. Why so they could breathe so they could hold things so they could bite so they could speak

The correct answer is A so they could breathe.

In ancient Egyptian beliefs, it was thought that opening the mummies’ mouths allowed the deceased to breathe in the afterlife, ensuring they could communicate with the gods and navigate the next world. This practice was part of preparations for the burial to help the soul in its journey after death.
