If the government converted the highway from 4 lanes into 6 lanes, then the increase in the number of lanes would have been 2. To calculate the percentage increase, we divide the increase by the original number and multiply by 100:

2/4 x 100 = 50%

If the government converted the highway from 6 lanes into 4 lanes, then the decrease in the number of lanes would have been 2. To calculate the percentage increase, we divide the decrease by the original number and multiply by 100:

2/6 x 100 = 33.33%

Therefore, the best choice is B, as it correctly identifies the percentage increase in each scenario.
