Linnaeus is credited with the following

The correct option is Binomial nomenclature.

Carl Linnaeus, a Swedish botanist, zoologist, and physician, is widely celebrated as the "Father of Modern Taxonomy." His most famous contribution to science was the introduction and standardization of binomial nomenclature, which is the formal system of naming species of living organisms.

Before Linnaeus developed this system, scientists used long, descriptive Latin phrases to name organisms, which was highly impractical and inconsistent. Linnaeus simplified this by introducing a two-part naming system:
1. The first word represents the Genus (shared by closely related species, capitalized).
2. The second word represents the specific epithet (identifies the specific species, written in lowercase).
For example, the scientific name for humans is Homo sapiens, and for the house cat, it is Felis catus.

Here is why the other options are not credited to Linnaeus:
- Law of Limiting factor: This is a principle in plant physiology and ecology formulated by F. F. Blackman in 1905.
- Concept of inheritance and Theory of heredity: These foundational concepts of genetics were established by Gregor Mendel through his systematic hybridization experiments on pea plants.
