Answer:
B. Multiple organisms can have the same common name
Step-by-step explanation:
You want to know why scientists use scientific names instead of common names when they classify organisms.
Naming
Common names may be based on general appearance, behavior, or habitat, so may be applied to organisms of different species. For example, there are about 56 different species of the animal called a "rat."
Scientific names are used for classification so the identification can be more precise. This avoids the problem that multiple organisms can have the same common name.
