D) Oersted - 18th century, Ampère - 19th century, Faraday - 19th century, Tesla - 20th century.

Answer 1

The contributions of Oersted, Ampère, Faraday, and Tesla were all made between the 19th and 20th centuries, with Oersted's discovery in 1820, Ampère's work following shortly after, Faraday's induction discovery in 1831, and Tesla's advancements in AC power systems in the late 19th and early 20th centuries.

Step-by-step explanation:

The correct timeline of contributions by Oersted, Ampère, Faraday, and Tesla is as follows:

• Hans Christian Oersted - 19th century: In 1820, he demonstrated that electric currents create magnetic fields. This was a key discovery that linked electricity and magnetism, laying the foundation for the study of electromagnetism.
• André-Marie Ampère - 19th century: Soon after Oersted's discovery, Ampère furthered the understanding of electromagnetism through his studies of the forces exerted by electric currents on each other.
• Michael Faraday - 19th century: In 1831, Faraday showed that moving a wire through a magnetic field could induce an electric current. This finding led to the invention of the electric motor and the electric generator, revolutionizing the use of electrical power.
• Nikola Tesla - 19th and 20th centuries: Tesla made numerous contributions to the field of electricity and magnetism in the late 19th century and carried on into the early 20th century, including the development of alternating current (AC) electrical systems.

Therefore, the correct answer to the question is C) Oersted - 19th century, Ampère - 19th century, Faraday - 19th century, Tesla - 20th century.
