The most correct definition of genus may be :-

Options

A. Genus is an aggregate of distantly related species
B. Genus is a group of species present in a given area
C. Genus is an aggregate of closely related species
D. Genus is a group of species present in a common habitat

Answer

To solve the question regarding the most correct definition of "genus," we can follow these steps:

### Step 1: Understand the term "genus"
- Genus is a taxonomic rank in biological classification. It is positioned between the family and species levels.

### Step 2: Analyze the provided options
- **Option A**: Genus is an aggregate of distinctly related species.
- **Option B**: Genus is a group of species present in a given area.
- **Option C**: Genus is an aggregate of closely related species.
- **Option D**: Genus is a group of species present in a common habitat.

### Step 3: Evaluate the definitions
- **Option A** suggests that the species are distinctly related, which is not accurate as genus typically includes closely related species.
- **Option B** focuses on the geographical aspect, which is not a defining characteristic of a genus.
- **Option C** states that genus is an aggregate of closely related species, which aligns with the biological definition of genus.
- **Option D** also emphasizes habitat, which again does not define genus correctly.

### Step 4: Determine the most correct definition
- Based on the analysis, **Option C** is the most accurate definition of genus as it captures the essence of what a genus represents in biological classification.

### Conclusion
The most correct definition of genus is: **"Genus is an aggregate of closely related species."**
