A. Type I is part of innate, nonspecific immunity, while type II is part of adaptive, specific immunity.

B. Type I binds to extracellular pathogens, while type II binds to intracellular pathogens.

C. Type I includes interferon-alpha and interferon-beta, while type II includes interferon-omega.

D. Type I interferes with viral replication, while type II activates white blood cells.

A. Type I is part of innate, nonspecific immunity, while type II is part of adaptive, specific immunity.

Explanation:

Type I interferons: Are produced early on during infection and are responsible for activation of the innate immune response, e. g Natural Killer cells.

Type II interferons: Are produced as part of the innate immune response and act as a link between innate immune response and activation of the adaptive immune response.
