b. Ectoparasite
c. Endoparasite
d. Facultative parasite GRADESMORE.COM
ANS: C
RATIONALE: Endoparasites live inside the host. Ectoparasites live on the outside of the host.
Facultative parasites can liveạs well outside the hostạs inside the host; host infection usually
occursạccidentally. Otherạccidental parasites may include parasites that usually infect
otherạ nimals.
