In the Linnean taxonomical system There are more organisms at the species level than at the genus level.

The correct option is D.

Explanation:

Carl Linnaeus is the father of taxonomy. His idea of classification is widely accepted and called as modern classification.

He categorized 7 levels based on the hierarchy as Kingdom, phylum , class, order, family, genus, species.

The Kingdom Animalia is the highest level of classification and species comes last.

The binomial nomenclature by him has made it very popular where distinguished species are categorized and is universal. In binomial nomenclature genus comes first (starts with capital letter) and species comes later (starts with small letter).

One genus will have many species. for example:

African lion  Panthera leo   (genus species)

Asian lion  Panthera leo leo

So one genus will have many species in it.

the missing space is phylum
