Which practice is an example of Replacement within the 3Rs framework?

Explanation:
Replacement means using non-animal methods instead of animals whenever possible, such as in vitro systems, computer modeling, or human-relevant data. This option aligns with that idea by describing substituting non-animal methods for animal use. The other approaches target different aims: refining how experiments are conducted to lessen pain or distress during procedures, reducing the number of animals used overall, or, in this case, increasing the number of animals—which runs counter to the goal of limiting animal use. So substitution with non-animal methods is the direct embodiment of Replacement within the 3Rs.
