Question

as we move down the levels of the taxonomic system towards species, each level becomes more...
random.
inclusive.
broad.
specific.

Explanation:

In the taxonomic system (used in biology, a subfield of Natural Science), the levels go from broad, general categories (like kingdom) down to species. As we move down (e.g., from phylum to class to order, etc., towards species), each level groups organisms with more shared characteristics, meaning the group is more specific. "Random" is incorrect as taxonomy is systematic. "Inclusive" and "broad" are opposite to the trend—lower taxonomic levels include fewer organisms with more precise traits, so they are more specific.

Answer:

D. specific.
