Binomial Nomenclature was given by

The correct answer is Carolus Linnaeus.

Step-by-Step Explanation:

1. Understanding Binomial Nomenclature: Binomial nomenclature is a formal, standardized system naming species of living things by giving each a name composed of two parts: the genus name (capitalized) and the specific epithet (lowercase). Both names are written in italics (or underlined when handwritten).

2. Historical Context: While the concept of using two names was introduced earlier by Gaspard Bauhin, it was the Swedish botanist and taxonomist Carolus Linnaeus who formalized, popularized, and consistently applied this system across the biological world in his landmark publications, most notably Species Plantarum (1753) for plants and Systema Naturae (1758) for animals.

3. Evaluating the Other Options:
- Ernst Mayr: A prominent 20th-century evolutionary biologist known for his work on the biological species concept, not binomial nomenclature.
- Darwin (Charles Darwin): Famous for formulating the theory of evolution by natural selection in On the Origin of Species (1859).
- Lamarck (Jean-Baptiste Lamarck): Known for his early theory of evolution based on the inheritance of acquired characteristics (Lamarckism).

Therefore, the system of binomial nomenclature was officially introduced and established by Carolus Linnaeus.
