Answer:
The correct answer is letter "B": Social trends.
Step-by-step explanation:
Many factors could increase the demand for a good or service. Changes in income, consumer patterns, governmental regulations, or social trends are some examples. Social trends refer to ideas or behaviors accepted by communities not necessarily because of an objective reason but because all participants in an economy are adopting those ideas or behavior. Not eating red meat or, most recently, becoming a vegan can be accepted by masses just because others accept it or associate it with a higher standard of living not necessarily that being true.
Therefore, the decrease in sales of the potato chip and snack food company is being affected by social trends since more people started to eat healthier snack foods leaving salty snacks aside.
