b. neither participant can survive or reproduce without the interaction
c. the participants will potentially engage in interspecific competition for resources
d. neither participant requires the interaction for survival or reproduction
e. convolution may result from the interaction
Answer-.
Option b ) neither partner can can survive or reproduce without the interaction. Is not true!
In facultative mutualism the interacting species are not fully dependant on each other for survival, the species can survive or reproduce without the other. An example is bee and flowers , a bee can feed nectar on any species of flower and similarly a flower can be pollinated by any other species of insects. It it not necessary for a bee itself to polinate the flower.
If this helps please give it a positive rating thank you!
