Answer

To solve the question regarding the projecting ridge found in the saccule and utricle, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks about a specific structure found in the saccule and utricle, which are parts of the inner ear involved in balance.

2. **Identify the Options**: The options given are:
- A) Macula
- B) Ampulla
- C) Cristae
- D) Both B and C

3. **Analyze Each Option**:
- **Macula**: The macula is indeed a structure found in both the saccule and utricle. It is responsible for detecting linear acceleration and the position of the head relative to gravity.
- **Ampulla**: The ampulla is a structure associated with the semicircular canals, not the saccule and utricle.
- **Cristae**: Cristae are sensory structures found in the ampullae of the semicircular canals, not in the saccule and utricle.
- **Both B and C**: Since both ampulla and cristae are not related to the saccule and utricle, this option is incorrect.

4. **Conclusion**: The correct answer is **A) Macula**, as it is the projecting ridge found in the saccule and utricle.

### Final Answer:
The saccule and utricle contain a projecting ridge called **macula**.
