Explanation

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about the effects of noise and which option correctly identifies a cause related to noise.

2. **Analyzing Each Option**:
- **Option A**: "Headache by constricting blood vessels of brain."
- This is incorrect. Noise typically causes headaches by dilating blood vessels, not constricting them.

- **Option B**: "Eye strain by constricting the pupil."
- This is also incorrect. Noise can lead to eye strain, but it is associated with the dilation of the pupil, not constriction.

- **Option C**: "Digestive spasms through anxiety."
- This option is plausible. Noise can create anxiety, which may lead to digestive issues and spasms.

- **Option D**: "High blood pressure by decreasing cholesterol level in blood."
- This is incorrect. Noise can lead to high blood pressure, but it does not decrease cholesterol levels; rather, it can increase stress levels which may affect cholesterol.

3. **Identifying the Correct Answer**: After analyzing all options, the only option that correctly associates a cause of noise is **Option C: Digestive spasms through anxiety**.

4. **Conclusion**: The correct answer to the question about the cause of noise is Option C.
