C. 6 times
D. `3-4` times

Answer

To determine how many times a cockroach molts from egg laying to the development of an adult, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Life Cycle of Cockroaches**: Cockroaches undergo a life cycle that includes several stages: egg, nymph, and adult. The nymph stage is where molting occurs.

2. **Identify the Molting Process**: Molting is the process where the cockroach sheds its exoskeleton to grow. This process is crucial for the development of the cockroach from a nymph to an adult.

3. **Count the Number of Molts**: According to the information provided, a cockroach will molt multiple times during its nymph stage. The number of molts can vary depending on the species and environmental factors.

4. **Refer to the Given Options**: The options provided for the number of molts are:
- 10 to 12 times
- 9 times
- 6 times
- 3 to 4 times

5. **Determine the Correct Answer**: Based on the information from the video transcript, it is stated that the number of moltings in cockroaches after hatching and during development is more than 10 times. Therefore, the correct option is **10 to 12 times**.

6. **Conclusion**: From egg laying to the development of an adult cockroach, the number of molting occurrences is **10 to 12 times**.
