A certain brand of pest repellent has been shown by several independent gardening journals to be ineffective in keeping away many of the most harmful breeds of aphid. Nonetheless, sales of this brand of pest repellent have remained robust throughout the greater Atlanta region, which has historically had one of the highest aphid concentrations in the United States.

Which of the following can be most reasonably concluded based on the above information?

A. Atlanta gardeners do not typically read gardening journals

B. The aphid population of Atlanta has declined dramatically in recent years.

C. The manufacturers of this pest repellent have deliberately misled consumers regarding its effectiveness against aphids.

D. Aphids are not the only potentially harmful garden pests in high concentration in the Atlanta region.

E. When used in combination with a stronger pest repellent, this one is particularly effective in keeping away all kinds of aphids.

D . even after having high popln of aphids in Atlanta ->the sales of pest repellant is high
which means although ineffective on few aphids but could be effective on other garden pests

Correct me if my thinking is wrong

For D to be the answer something in the argument has to link the pest repellant with effectiveness against other pests....

Nor can we make that assumption since these are not assumption family questions...this is an inference family question...

Unless somebody changes my opinion i am not taking D as the answer

I marked option E, and this option is wrong. In spite of inefficacy, one certain brand is popular in the Atlanta region because it has some good effects. As per option E, when combined with stronger pest repellent, this brand works best, so I marked it.
The reason I didn't choose option D because as per this option Aphids are not the only harmful pests. Okay, there may be other harmful pests also, and that is the only thing we know. Aphid can be effective for this pests or not.

Can someone please explain where did I go wrong, and is this an inference type question?

regards,
Arup
