Marketers need to understand how consumer needs and motivations impact

purchase for several reasons, including:

The development of marketing communications that convey a functional or

emotional value proposition that is aligned with fulfilling the need consumers have

identified and are trying to fulfill

The timely launch of those marketing communications so that consumers see those

messages as they are discovering the needs, wants, and tensions to be fulfilled or

alleviated

The development of new products, features, experiences, and wholescale innovation

that can better meet consumers' goals

All of these are correct
