Some of the Viruses That Infect Archaeal Cells Have Linear

Some of the viruses that infect archaeal cells have linear dsDNA genomes with covalently closed ends.What is a major advantage of this feature?

A) It makes the genome more stable under low pH conditions.
B) It allows the genome to be more easily packaged into the virion
C) It allows the genome to be more easily integrated into the host cell genome.
D) It allows the genome to use a self-priming mechanism for DNA replication.
E) All of the above are correct.
