Based on the information you provided, if the scatterplot shows a trend where generally, as the price of an item increases, the number of items sold decreases, then the valid inference would be:

B: In general, as the price of an item increases, the number of items sold decreases.

This suggests a negative correlation between price and quantity sold, which is a common observation in retail contexts.
