Think of a timeline as divided by the moments when a new technology changes society. The start of the automobile age is the moment when cars stop being a novelty and become a defining force in transport, industry, and daily life. That milestone signals the beginning of that era, so it’s the best choice because it explicitly marks the transition into the automobile period.

The other options point to later, separate eras—space exploration defines the Space Age, while computing and information infrastructure define the Digital/Information Ages. They don’t mark the start of the automobile era itself. Historical markers in this context typically anchor the automobile era around the late 19th to early 20th century, when cars began to reshape society.
