Options

A. Vernacular
B. Polynomial
C. Trinomial
D. Binomial

Answer

### Step-by-Step Solution:

1. **Understanding Nomenclature**: Nomenclature refers to the system of naming organisms scientifically. It is crucial for the classification and identification of living organisms.

2. **Historical Context**: The question pertains to the medieval period, specifically around the 15th to 17th centuries. During this time, various naming systems were used to classify organisms.

3. **Types of Nomenclature**:
- **Vernacular Nomenclature**: This refers to common names used in local languages, which lack a scientific basis.
- **Polynomial Nomenclature**: This system involved naming organisms using multiple terms, typically more than two. This was the prevalent system during the medieval period.
- **Binomial Nomenclature**: Introduced later, this system uses two names (genus and species) to identify organisms.
- **Trinomial Nomenclature**: This system includes three names (genus, species, and subspecies) and was introduced after the polynomial system.

4. **Identifying the Correct Answer**: Given that polynomial nomenclature involved naming organisms with more than two terms and was prevalent during the medieval period, the correct answer is **Polynomial Nomenclature**.

### Final Answer:
The nomenclature type prevalent in the medieval period was **Polynomial Nomenclature**.
