9. It is not known whether bovine spongiform encephalopathy (BSE), a disease of cattle invariably deadly to them, can be transmitted directly from one infected animal to another at all stages of the infection. If it can be, there is now a reservoir of infected cattle incubating the disease. There are no diagnostic tests to identify infected animals before the animals show overt symptoms. Therefore, if such direct transmission occurs, the disease cannot be eradicated by______

Which one of the following best completes the argument?

(A) removing from the herd and destroying any diseased animal as soon as it shows the typical symptoms of advanced BSE
(B) developing a drug that kills the agent that cause BSE, and then treating with that drug all cattle that might have the disease
(C) destroying all cattle in areas where BSE occurs and raising cattle only in areas to which BSE is known not to have spread
(D) developing a vaccine that confers lifelong immunity against BSE and giving it to all cattle, destroying in due course all those animals for which the vaccine protection came too late
(E) developing a diagnostic test that does identify any infected animal and destroying all animals found to be infected

A - before the animals are removed, the disease could have already spread to other animals in the herd

Agree with (A). And since no diagnostic tests exist, it wont be possible to tell which ones were recently infected. The disease goes on.
