There has been two eons in the Earth's geologic history so far, the Precambrian eon, and the Phanerozoic eon. The eons are the basic and by far longest units on the geological time scale, spreading over hundreds of millions of years.
The Precambrian eon is the eon that starts with the formation of the Earth, up until the development of multi-cellular organisms. A very important event in this eon can be considered the formation of the Earth's oceans, which later enabled the conditions for the development of life. The organisms that dominated this eon are the one cellular organisms.
The Phanerozoic is the eon in which the multi-cellular organisms started to develop and evolve. This eon started with the end of the Precambrian eon, 543 million years ago up until the present. A very important event in this eon is the change of the composition of the atmosphere, which enabled the terrestrial life, as well as the better living conditions for the marine life. It is very hard to choose a dominant form of life in this eon, but worthy of mentioning are the plants, the sinapsids, dinosaurs, mammals, fish.
The discarded theory of blending inheritance most closely resembles incomplete dominance.

What is blending inheritance?</h3>
- An antiquated biological notion from the 19th century is the concept of blending inheritance.
- According to the hypothesis, children inherit any trait by averaging the values of their parents for that trait.
- According to the theory of blended inheritance, an offspring combines the values of both parents for a given attribute.
- As opposed to blended inheritance, particulate inheritance states that a child inherits individual units or genes from each parent.
- Offspring thus combines the traits of both parents.
- Incomplete dominance is the term used to describe phenotypic "blending" of two features, which implies that neither trait is truly dominant over the other.
- The manifestation of phenotypic traits that are intermediate between those of the parents, such as pink flower color from red and white parents.
- Inheritance was a now-discredited hypothesis that claimed children's genetic make-up was a pure admixture of their parents'.

The answer would be D, because that is the only logical one, and selling 15 cups is not a hypothesis, it is a fact.
D is the one hypothesizing that he will make a profit.
Hope this helps and have a nice day:)
