Answer: Option (A) is the correct answer.

Explanation:

Electromagnet is a device in which an iron core is surrounded by a coil of insulated wire. When an electric current is passed through this insulated wire then it results in the formation of a magentic field.

As a result, magnetic force is created.

Thus, we can conclude that a magnetic force cannot be created in an electromagnet without an electric current.

The taxonomic classification system was invented by Carl Linnaeus. It is a hierarchical model of classifying living organisms based on shared characteristics.

Dogs are referred to as 'man's best friend' partly owing to some level of taxonomic relationship between the two species. Dogs and man belong to a class of vertebrates known as mammals- one of the shared characteristics of mammals is that they give birth to their young ones alive.

The taxonomic classification of man is:

Domain: Eukaryote - Kingdom - Animalia Phylum - Chordata Subphylum - Vertebrata Class - Mammalia Order - Primates Family - Hominidae Genus - Homo Species - sapiens.

The taxonomic classification of dog is:

Domain: Eukaryote - Kingdom - Animalia Phylum - Chordata Subphylum - Vertebrata Class - Mammalia Order - Carnivora Family - Canidae Genus - Canis Species - lupus familiaris
