Answer 1

I think it would be A

Answer 2

The correct answer is option A. "organisms that use the same resource". In Biology, a competitive relationship is defined by an interaction of organisms or species where all the indivuals are at risk for some reason. Organisms that use the same resource would led to this kind of relationship, as the lack of the resource is harmful for all the organisms involved.
