The correct answer is option 'B' which is Bakelite.
Explanation:
- Bakelite was the first synthetic plastic invented by Belgian chemist Leo Baekeland in 1907.
- Bakelite was created by combining phenol and formaldehyde under heat and pressure to create a hard, durable material that could be molded into various shapes.
- Bakelite was a major breakthrough in the plastics industry, as it was the first plastic that could be molded into complex shapes and was heat-resistant and non-conductive.
- Bakelite was widely used in electrical and automotive industries for its heat-resistant and insulating properties.
- After the invention of Bakelite, other types of plastics such as nylon, PVC, and polystyrene were developed in the following years, leading to the growth of the plastics industry.
