In the book of Hebrews, what is the significance of Melchizedek in relation to Jesus' priesthood?

A Melchizedek was a Levite priest, establishing Jesus' lineage through the Levitical priesthood. B Melchizedek's priesthood was based on lineage, similar to Aaron's, which Jesus fulfilled perfectly. C Melchizedek's priesthood was superior to the Levitical priesthood and based on an indestructible life, prefiguring Jesus' eternal priesthood. D Melchizedek was merely a symbolic figure with no real connection to Jesus' priestly role.
