‘Equus caballus’ is the scientific name of which of the following animals?

Horse

The correct answer is Option (2)-Horse

The scientific name 'Equus caballus' is used to specifically identify the domesticated horse. Scientific names are based on the principles of binomial nomenclature, a system introduced by the Swedish botanist and physician Carl Linnaeus. In this system, each species is given a unique two-part name consisting of the genus (generic name) and the species identifier.

• Genus: "Equus" refers to the genus, which encompasses various species of large, hoofed mammals, including horses, donkeys, and zebras.
• Species: "caballus" is the specific epithet that distinguishes the domesticated horse within the genus Equus.

So, 'Equus caballus' is the formal scientific name used to precisely denote the domestic horse.
