B. two carbonium ions
C. two carbanions
D. one cation and one anion.

Explanation

To solve the question regarding the heterolytic fission of the C—Cl bond, we need to understand the nature of the bond and the process of heterolytic fission.

### Step-by-Step Solution:

1. **Understanding Heterolytic Fission**:
- Heterolytic fission refers to the breaking of a bond where both of the shared electrons are taken by one of the atoms involved in the bond. This results in the formation of charged species.

2. **Analyzing the C—Cl Bond**:
- The carbon-chlorine (C—Cl) bond consists of a carbon atom and a chlorine atom. Chlorine is more electronegative than carbon, meaning it has a stronger tendency to attract electrons.

3. **Charge Distribution**:
- Due to the difference in electronegativity, when the C—Cl bond undergoes heterolytic fission, the bond pair of electrons is pulled towards the chlorine atom. This results in:
- Chlorine acquiring a negative charge (anion, Cl⁻).
- Carbon acquiring a positive charge (cation, C⁺).

4. **Result of Heterolytic Fission**:
- Therefore, the heterolytic fission of the C—Cl bond will produce one cation (C⁺) and one anion (Cl⁻).

5. **Conclusion**:
- The correct answer to the question is: **one cation and one anion**.

### Final Answer:
- The heterolytic fission of the C—Cl bond produces **one cation and one anion**.
