Options

A. Na
B. Ca/k
C. Mg
D. Cl.

Answer

### Step-by-Step Solution:

1. **Understanding Endolymph**:
- Endolymph is a fluid found in the inner ear, specifically within the membranous labyrinth. It plays a crucial role in the functioning of the auditory and vestibular systems.

2. **Composition of Endolymph**:
- The primary ions present in endolymph are potassium (K+) and calcium (Ca2+). Among these, potassium is present in higher concentrations.

3. **Identifying the Correct Ion**:
- Given the options:
- Sodium (Na+)
- Calcium (Ca2+)
- Potassium (K+)
- Magnesium (Mg2+)
- Chlorine (Cl-)
- The question asks which ion is present in good quantity in endolymph.

4. **Conclusion**:
- Based on the understanding of the composition of endolymph, we conclude that endolymph has a good quantity of **Potassium (K+)**.

### Final Answer:
Endolymph has a good quantity of **Potassium (K+)**.
