a. where the organism lives
b. the genes of the organism
c. the shape of the organism
d. how small the organism is

Explanation:

When classifying organisms, the genes (genetic material) of the organism are of utmost importance. Genetic similarities and differences help in determining evolutionary relationships and classifying organisms into different taxonomic groups. The habitat (where the organism lives - option A), shape (option C), and size (option D) can be more variable and less fundamental compared to genetic makeup for classification purposes.

B. the genes of the organism
