The correct answer is option C, that is, behavioral isolation.
The phenomenon of behavioral isolation takes place when two populations possess the tendency of interbreeding, but exhibit distinctions in courtship rituals or other kinds of behavior. For example, the western and eastern meadowlarks are very identical birds whose habitat overlap in the middle of the United States.
However, the members of the two species will not mate with each other, possibly as they use different songs in order to fascinate males. The eastern meadowlarks will not respond to the songs of western meadowlarks, and vice versa.
Fungi contain many different microscopic organisms compared to regular plants, Fungi can be very poisonous compared to plant too and also a regular plant contains a cell wall where as Fungi don't. Most importantly plants use the process photosynthesis to make their own food, Fungi don't.
I believe the correct response is D. Need a living host cell to reproduce.
The Correct Answer is: D. 1,2,4
