D. 5

Answer

To solve the question regarding the number of semicircular canals in the utriculus of a frog, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure**: The utriculus is a part of the inner ear in frogs and is associated with balance and spatial orientation. It contains semicircular canals.

2. **Identify the Semicircular Canals**: In frogs, there are three semicircular canals that are oriented approximately perpendicular to each other. These canals are crucial for detecting rotational movements.

3. **Name the Semicircular Canals**:
- **Anterior Semicircular Canal**: Also known as the superior semicircular canal.
- **Posterior Semicircular Canal**: Known as the inferior semicircular canal.
- **Horizontal Semicircular Canal**: Sometimes referred to as the external semicircular canal.

4. **Count the Semicircular Canals**: Based on the identification, we can conclude that there are three distinct semicircular canals present in the utriculus of a frog.

5. **Select the Correct Option**: The options given are four, two, three, or five. Since we identified three semicircular canals, the correct answer is three.

### Final Answer:
The utriculus of the frog has **three** semicircular canals.
