Which numerical range best describes the share of rodents used in biomedical research?

Explanation:
Rodents dominate the animal use in biomedical research because they are small, inexpensive to maintain, breed quickly, and have well-developed genetic and disease-model resources. This combination means that mice and rats make up the vast majority of animals used, typically around 90–95 percent in many reports and datasets. The other ranges would understate or overstate this reality: 100% would ignore non-rodent species still in use, while 50–60% or 10–20% would fail to reflect how dominant rodents are in research practices.
