If the conclusion is that the doctors claim they can produce a vaccine that will produce permanent immunity to that disease then how does A ( most young people who contract hepatitis E are young adults who were probably exposed to the virus in childhood) counter the argument? If they have a cure, then giving it to infants would produce permanent immunity from that disease in the future. They never claim it can wipe out everything currently existing, so it seems answer A is irrelevant.
