Answer: C) Thomas Edison


Explanation:

Thomas Edison is widely credited with inventing the practical incandescent light bulb. While he wasn't the first person to create an electric light, Edison developed the first commercially viable light bulb that could burn for many hours without burning out. His breakthrough came in 1879 when he successfully created a light bulb that could glow for over 1,200 hours using a carbonized bamboo filament.


Before Edison's success, many inventors had tried to create electric lighting, but their bulbs either burned out too quickly or were too expensive to produce. Edison's genius lay not just in improving the light bulb itself, but in creating an entire electrical system. He developed the power stations, electrical wires, and distribution systems needed to bring electricity to homes and businesses.


Let's look at why the other options are incorrect. Alexander Graham Bell is famous for inventing the telephone, not the light bulb. Nikola Tesla was a brilliant inventor who contributed significantly to the development of alternating current (AC) electrical systems, but he didn't invent the light bulb. Michael Faraday was a pioneering scientist who discovered electromagnetic induction and laid the groundwork for electric motors and generators, but he also didn't create the light bulb.


Edison's light bulb invention was the result of systematic experimentation. He and his team at Menlo Park tested over 3,000 different materials for the filament before finding the right combination that would glow brightly without burning out quickly. This methodical approach to invention made Edison one of history's most successful innovators, earning him over 1,000 patents during his lifetime.


The impact of Edison's light bulb invention cannot be overstated. It revolutionized how people lived and worked, extending productive hours beyond daylight and making indoor activities safer and more convenient. His invention laid the foundation for the modern electrical age and transformed cities around the world. Today, while we use more efficient LED and CFL bulbs, we still owe our electric lighting systems to Edison's pioneering work in the late 1800s.
