A Correct answer
Explanation

Google's search index has grown to encompass billions of web pages. 8 billion represents a realistic estimate of the scale of Google's index in the late 2000s when this question was likely written. 80 million would be far too small for the world's largest search engine, while 8000 million and 8000 billion are unrealistic figures.
