The correct answer is:
Option 1: Carolus Linnaeus
Carolus Linnaeus (also known as Carl Linnaeus) introduced the system of binomial nomenclature in the 18th century. This system gives each species a two-part Latin name: the genus name (capitalized) and the species name (lowercase), for example, Homo sapiens.
Linnaeus is also known for his work in classifying organisms and developing the modern system of taxonomy.
The other options are incorrect because:
Ernst Haeckel (Option 2) was a German biologist known for his work in the development of the concept of ecology and the tree of life, but he did not develop binomial nomenclature.
Gaspard Bauhin (Option 3) was a Swiss botanist who contributed to plant classification but did not introduce binomial nomenclature.
John Ray (Option 4) was an English naturalist who contributed to the early stages of taxonomy but did not establish the binomial naming system.
Thus, Carolus Linnaeus is credited with introducing binomial nomenclature.
Binomial nomenclature, the system of naming organisms with a two-part name (genus and species), was introduced by Carolus Linnaeus.
Linnaeus's system provided a standardized and universally recognized way to identify and classify organisms, which is still used today.

A block of certain mass is placed on a rough floor. The coefficients of static and kinetic friction between the block and the floor are 0.4 and 0.25 respectively. A constant horizontal force \( F = 20 \, \text{N} \) acts on it so that the velocity of the block varies with time according to the following graph. The mass of the block is nearly (Take \( g = 10 \, \text{m/s}^2 \)):
A wooden block of mass M lies on a rough floor. Another wooden block of the same mass is hanging from the point O through strings as shown in the figure. To achieve equilibrium, the coefficient of static friction between the block on the floor and the floor itself is
The circuit shown in the figure contains two ideal diodes \( D_1 \) and \( D_2 \). If a cell of emf 3V and negligible internal resistance is connected as shown, then the current through \( 70 \, \Omega \) resistance (in amperes) is:
