The correct answer is (a) U.S.A.
In February 2015, Google conducted the first public trial of its self-driving car technology in Mountain View, California. The trial was expanded to three other cities in the U.S. in the following months: Austin, Texas; Phoenix, Arizona; and Kirkland, Washington.
The trial was a success, and Google has since expanded its self-driving car program to other cities around the world. In 2016, Google began testing its self-driving cars in Japan. In 2017, Google began testing its self-driving cars in Germany. And in 2018, Google began testing its self-driving cars in Great Britain.
Google is not the only company working on self-driving car technology. Other companies, such as Uber, Lyft, and Tesla, are also developing self-driving car technology. It is likely that self-driving cars will become a common sight on our roads in the near future.
