Answer:
a. minimalists
Step-by-step explanation:
The exclusionists group are people who who advocates the exclusion of anything or a principle an on this case not makes sense to the concept analyzed here since they not use animals to conduct a research.
The abolitionists are people who want to end some paradigm, but they not include the animals in the research.
The inclusionists are people who are not related to the use of animals in order to conduct a research so this is not the correct option.
And Minimalists are the correct choice since and are people who based their research on the animals.
