If you were to read the statement out loud, you would say option 2. If you read the number and wanted to interpret it for someone, option 1 would be better. If you wanted to write the number, option 1 would be the best way to write it. There is less confusion with option 1.

3.5 billion years In English we would rarely say Option 2 or 3, although option 2 may be written occasionally.

For me Option 2 sounds more natural. Three thousand five hundred millions...
