Answer: B

Explanation:

To find the month that had the biggest increase in average sales compared to the previous month in 2019, you need to compare the slopes of the line segments between each pair of months. The steeper the slope, the greater the increase. Based on the line chart, October had the steepest slope, meaning it had the biggest increase in average sales compared to September in 2019.
