B)develop into a virus with a different host range.
C)become capable of human-to-human transmission.

Accepted Answer

For H5N1 avian flu virus to cause a human pandemic, it would need to acquire the ability to transmit from human to human. Currently, human infections are mostly the result of direct contact with infected birds or their secretions. However, if the virus were to undergo genetic changes that allow it to spread more easily between humans, it could potentially cause a global outbreak.
