D. 2 & 4

Answer

To solve the question regarding the statements about conditioned reflexes, let's analyze each statement one by one.

1. **Statement (1): Acquired by practice or learning.**
- Conditioned reflexes are indeed learned behaviors. They are not innate but are developed through experience and practice. This statement is **correct**.

2. **Statement (2): Does not abolish by lack of practice.**
- Conditioned reflexes can weaken or diminish over time if not practiced. They are not permanent and can fade without reinforcement. Therefore, this statement is **incorrect**.

3. **Statement (3): Participation of cerebral cortex.**
- The cerebral cortex plays a significant role in conditioned reflexes, as it is involved in higher cognitive functions such as memory and learning. This statement is **correct**.

4. **Statement (4): Originates spontaneously.**
- Conditioned reflexes do not originate spontaneously; they are learned responses to specific stimuli. This statement is **incorrect**.

### Conclusion:
Based on the analysis:
- The correct statements regarding conditioned reflexes are **(1) and (3)**.
