The correct options are
A Mutualism: species A (+) and species B (+).
B Competition: species A (-) and species B (-).
D Parasitism: parasite (+) and host (-).
Mutualism is a type of interaction in which both the organisms involved benefit from each other. So, both species A and B are beneficial: species (+) and species B (+).
In competition, the interacting organisms compete for the same limiting resouces. So, both species A and B have detrimental interaction: species A (-) and species B (-).
In predation interaction, the beneficial organism is known as predator while the detrimental one is called prey: predator (+) an d prey (-).
In parasitism, the parasite is beneficial while the host organism is harmed by the parasite: parasite (+) and host (-).
