An argument states: "Since 'Happy Paws' pet store saw a 20% increase in dog food sales after they started playing classical music in their store, it's clear that classical music makes customers more likely to buy dog food." Which of the following alternative explanations would most strongly undermine the conclusion?

✓ Correct Answer: Option B

The argument attributes increased sales solely to classical music. Providing other plausible, significant reasons for the sales increase (like competitor closure or a new dog park bringing more dog owners to the area) directly weakens the original conclusion by offering strong alternative causes.
