Answer:
The correct answer is letter "A": Relative advantage.
Explanation:
American Professor E.M. Rogers (1931-2004) in his book "Diffusion of Innovation" (1962) defined Relative Advantage like the degree to which a consumer observes a new product enhanced than its substitute. Nowadays the concept of relative advantage denotes the degree in which customers perceive the benefits of a new product higher than existing competitors.
The adoption of new products will rely on the relative advantage they can provide to consumers.
