First, you should not boldface your confused choices. You make other cannot improve through critical thinking. Second, just spoil your choices in the question. OK? Please, edit your question :D. Thank you so much.
Let's I try to help you:
New regulation will make the price of good increase => decrease the export
A. the need to comply with the new regulations will stimulate the development within Risemia of new pollution control equipment (NPCE) for which a strong worldwide demand is likely to emerge.
In this choice, you will realize that NPCE will become popular all over the world, and price of all product relate to that industry also increase while the demand is still remain comparably to the last year. So, export of Risemia will not be affected by increased price
D. By international standards, the levels of pollutants currently emitted by some of Risemia's manufacturing plants are not considered excessive.
Does it stick to price, the main factor affected to the export of Risemia? This choice talk about standard of good. Ok, before and after regulation. The quality of Risemia products is acceptable. It does not prove anything. Rights?
Hope that help.
