The plot below shows the relationship between the mortality risk of cardiovascular disease and the number of steps a person walks per day. Based on the data, which one of the following options is true?

Your answerChoose one option.

The risk reduction on increasing the steps/day from 0 to 1000 is less than the risk reduction on increasing the steps/day from 1000 to 2000.

The risk reduction on increasing the steps/day from 0 to 500 is less than the risk reduction on increasing the steps/day from 1500 to 2000.

For any 5000 increment in steps/day the largest risk reduction occurs on going from 0 to 5000.

For any 5000 increment in steps/day the largest risk reduction occurs on going from 1500 to 2000.
