To answer the question regarding what "Linn" refers to in the scientific name of the mango plant, Mangifera indica Linn, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Scientific Name**: The scientific name of an organism is composed of two parts: the genus name and the species name. In this case, "Mangifera" is the genus and "indica" is the species.

2. **Identifying the Author**: The term "Linn" or "Linnaeus" at the end of the scientific name indicates the author who first described the species. In this case, it refers to Carl Linnaeus, who developed the system of binomial nomenclature.

3. **Evaluating the Options**:
- **Option 1**: Variety of mango - This is incorrect because "Linn" does not refer to a variety.

- **Option 3**: A scientist who first described the mango plant - This is correct as it refers to Linnaeus.
- **Option 4**: A scientist who changed the name proposed by Linnaeus - This is incorrect; Linnaeus is the original namer.

### Final Answer:
Linn refers to a scientist who first described the mango plant (Carl Linnaeus).
