B. Cf and Ca
C. Cf and Cu
D. Ra and He

Answer

To answer the question "Oganesson has been synthetically produced by the collision of," we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Elements Involved**:
- Oganesson (Og) is a synthetic element that has been produced in laboratories.
- The elements known to be involved in the synthesis of Oganesson are Californium (Cf) and Calcium (Ca).

2. **Determine the Isotopes**:
- The specific isotopes used in the synthesis are Californium-249 (Cf-249) and Calcium-48 (Ca-48).

3. **Understand the Reaction**:
- When Californium-249 collides with Calcium-48, a nuclear reaction occurs that results in the formation of Oganesson (Og).
- The mass number of the resulting Oganesson is 294.

4. **Summarize the Reaction**:
- The reaction can be summarized as:
\[ \text{Cf-249} + \text{Ca-48} \rightarrow \text{Og-294} \]

5. **Select the Correct Answer**:
- Based on the information, the correct answer to the question is that Oganesson is produced by the collision of Californium-249 and Calcium-48.

### Final Answer:
Oganesson has been synthetically produced by the collision of Californium-249 (Cf-249) and Calcium-48 (Ca-48).
