The answer is B

OpenStudy (envy_seven):

You already know that the answer is not A or C because the graph clearly shows that it's decreasing

OpenStudy (envy_seven):

Then we only have B and D left. You can see that it decreases by half of one hundred thousand each year. Knowing this, after two years, you can add the two halves together and get 1 hundred thousand over 2 years. It's a linear decline meaning it declines at a set number, in this case it declines half of one hundred thousand each year, so no matter what number it's subtracting 1/2 from, it will always decrease by the set amount
