How does the antiparallel polarity of DNA strands contribute most to the integrity of genetic information?

A) A DNA double helix cannot be broken or degraded. B) The antiparallel polarity of the strands means that replication occurs more quickly, decreasing the likelihood of DNA damage. C) Hydrogen bonding between strands is very stable, so DNA bases cannot be not damaged by environmental agents. D) Both antiparallel strands can be replicated continuously, which is more accurate than discontinuous replication. E) Each antiparallel strand can serve as a template to produce the other strand in the event of DNA damage.
