Which of these lurks on tall plants and weeds waiting for a host to pass by? A) heartworm B) mosquito C) tapeworm D) tick

Based on my information, I would say the mosquito's would do this, but they actually don't. This would be handled by ticks, as they would either sometimes wait for a mate to come by, or in another sense, a host, as they would lurk as they could.

D tick, although tapeworms eggs can survive on plants and become ingested into the host
