If one B is made using 2 Ds and 2 Es, and one A is made using 3 Bs and 1 C, which is true?

1. A is the parent of B.

2. C is the parent of A.

3. A is one parent of D.

4. D and E are children of A.

The correct answer is: A is the parent of B.

The statement that A is the parent of B is accurate when assessing the relationships between these components. In this context, the term "parent" typically refers to an element that is used to create another element. In this case, since B is constructed from 2 Ds and 2 Es, these two elements are considered "children" of B. However, A is made up of 3 Bs and 1 C, indicating that A relies on Bs for its creation. Therefore, A can be seen as a higher-level component that derives its structure from B, which is consistent with the definition of "parent" in hierarchical structures. Understanding this hierarchy is important, as it highlights how components are interrelated in a production or assembly context. In contrast to the other statements, which either mischaracterize the relationships between the components or do not accurately reflect the construction process, recognizing A's role as the creator of B supports the conclusion that A is indeed the parent of B.
