Answer

To solve the question "The study of communities of various genera and species is called," we can follow these steps:

### Step 1: Understand the Terms
- **Community Ecology**: This is the study of the organization and functioning of communities, which are assemblages of interacting populations of different species.
- **Syn-Ecology**: This branch of ecology focuses on the relationships between groups of organisms or co-existing biological communities.

### Step 2: Analyze the Options
- **Option A: Community Ecology** - This is a valid term that refers to the study of communities of various genera and species.
- **Option B: Syn-Ecology** - This is also a valid term that refers to the study of relationships between groups of organisms in a community.
- **Option C: Aortic Ecology** - This term refers to the study of a single organism or a single species in relation to its habitat, which does not fit the question.
- **Option D: Both A and B** - Since both community ecology and syn-ecology are relevant to the study of communities of various genera and species, this option is correct.

### Step 3: Conclusion
Based on the definitions and analysis of the options, the correct answer to the question is **Option D: Both A and B**.
