Answer :

In common it should be an adjective. So I'd like to go with B.hazardous. It describes snakes.
Among the choices the word that the sentence functions as an objective complement  based on the sentence above is letter A considered. An object complement follows an object and clarifies what the transitive verb converted that direct object into.
