Prep Test 17 Section 4 Passage 3 #16

Could someone help me with why D is not the correct answer?
In the second paragraph, it gives the stats for carbon taxes and says "It should be noted, however, that these numbers ignore the effect of the tax on economic growth, and hence on emissions". Doesn't that imply that the taxes need to account for the effect on economic growth, and are thus influenced by it and would vary based on the effect that the tax would have on a country's economy (D)?
