Question

organisms are the same __________ when they can have offspring, then those have more offspring.
options: class, species, phylum, family

Explanation:

The biological concept of a species is defined as a group of organisms that can interbreed and produce fertile offspring. Class, Phylum, and Family are broader taxonomic categories where organisms within them do not necessarily have the ability to interbreed to produce viable offspring. So the correct term here is "Species".

Answer:

B. Species
