Final answer:
The abstract level in the hierarchy of theories where objects have similar shapes is called the Superordinate Level.
Step-by-step explanation:
In the hierarchy of theories, especially in the context of biological classification, the superordinate level is the most abstract level where objects share similar shapes or characteristics. This conceptual level is used to group entities that are alike in very broad ways but can be quite different in specifics. For example, the taxonomic classification system is hierarchical and allows living organisms to be organized based on evolutionary relationships and characteristics that become more specific at each sublevel. Therefore, the correct answer is A. Subordinate Level.
