It's probably just me, but I found this (to my cost) a rather misleading question.
There were two Egyptian gods of the dead: Anubis and Osiris. According to Wikipedia, "Anubis ... is the Greek name of the god of death, mummification, embalming, the afterlife, cemeteries, tombs, and the Underworld, in ancient Egyptian religion". A bit further on, Wikipedia tells us that "By the Middle Kingdom (c. 2055–1650 BC) he was replaced by Osiris in his role as lord of the underworld."
Wikipedia describes Osiris as "the god of fertility, agriculture, the afterlife, the dead, resurrection, life, and vegetation in ancient Egyptian religion."
Note that the prase "god of ... the dead" is used to refer to Osiris, but not to Anubis.
The word "jackal–headed" was of course a great big clue. I'm not making excuses; just saying that the question is misleading. Well I was misled by it anyway, and I'm still kicking myself over it. But that's not going to stop me having a go at the question setter!
And in any case, it wasn't a jackal's head; it was a wolf's head. Over to Wikipedia again: "Archeologists have identified Anubis's sacred animal as an Egyptian canid, the African golden wolf. The African wolf was formerly called the 'African golden jackal', until a 2015 genetic analysis updated the taxonomy and the common name for the species. As a result, Anubis is often referred to as having a 'jackal' head, but this 'jackal' is now more properly called a 'wolf'.
