The correct answer is letter "D": Innovators/Early adopters.

Explanation:

Healthcare equipment supplier A.G. Industries created the "Anti-Gravity Belt" in which the institution identifies five (5) types of consumer groups: innovators, early adopters, early majority, late majority, and laggards.

Innovators are those that play an important role in institutions introducing new products to the market since innovators are willing to pay higher prices to access first to technological advancements.  

Early adopters learn from what innovators have discovered to find practical uses to the innovation. These individuals are in charge of spreading those practical uses through different platforms influencing the purchase of the new technology.
