Answer:
The correct answer is c) People who defy existing laws to kill predators for money, animal parts, or personal reasons ar called poachers.
Step-by-step explanation:
The sentence expresses continuity rather than discontinuity, since it introduces a list of reasons that maintains certain relationship between them. In this case, the correct type of conjunction that fits the sentence must be a coordinating, not contrastive conjunction, relating the three reasons why a poacher might kill predators.
All other examples use contrastive conjunctions (yet, but), which makes no sense. Option B) is incomplete, lacking the element "to kill predators".
