Solution

The correct options are
A
Price of a product and its sales

C
Percentage body fat and number of hours of exercise

As the price of a product increases, people are less likely to buy it. Greater the number of hours spent exercising, greater will be the reduction in percentage body fat. These two examples show a negative correlation.
