C Correct answer
Explanation

Obligatory parasites survive within a host & directly pass from one to another,e.g.,  Trichomonas. Symbiosis is an animal association, an interaction between two biological species for their survival. In Neritic zone, water is constant. Facultative parasites are free living & accidentally infect a host. Lag phase is the slow growth phase.
