CorrectNot quiteAnswer B

Correct answer: B

The rise is $18{,}000 - 12{,}000 = 6{,}000$ users a day.
Measured on the January figure, $6{,}000 \div 12{,}000$ = ½, a rise of 50%. This follows.
"One-third" divides 6,000 by the June figure, 18,000, which is the wrong base. Fares and car use are not mentioned, so those need outside information.

Worth noting

A report of numbers supports only conclusions about those numbers. The reason behind the rise is a guess.
