When were airbags developed?

Answer: C — Early 1990's

Airbags were first developed in the late 1970s and had limited use in the 1980s, but they didn't become widely available and standard in vehicles until the early 1990s. This period marked a significant advancement in automotive safety technology, as it was during this time that manufacturers began to implement airbags extensively in response to safety regulations and consumer demand for safer vehicles. The early 1990s saw the introduction of airbags in many popular car models and the establishment of regulations requiring them in new vehicles, leading to a dramatic increase in their use to help protect occupants during collisions.
