B Correct answer
Explanation

Total commuters = 10 * 1200 = 12000. New average per trip = 12000 / 6 = 2000. Increase = 2000 - 1200 = 800.

AI explanation

The total number of commuters for the 10 trips is 10 multiplied by 1200, which equals 12000. When the trips are reduced to 6, the new average is the total commuters divided by 6, so 12000 divided by 6 is 2000. The average increase is the difference between the new average and the old average, which is 2000 minus 1200, resulting in 800.
