D. Obligate anaerobes can live in the presence of abundant oxygen.

Answer

To solve the question of identifying the correct statements regarding anaerobes, aerophiles, aerobes, and obligate anaerobes, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Evaluate the first statement: "Anaerobes grow in absence of oxygen."**
- **Analysis:** Anaerobes are organisms that do not require oxygen for their growth and can thrive in environments devoid of oxygen.
- **Conclusion:** This statement is **correct**.

2. **Evaluate the second statement: "Aerophiles can grow in complete absence of oxygen."**
- **Analysis:** Aerophiles are organisms that thrive in the presence of oxygen. They are oxygen-loving organisms and cannot grow without it.
- **Conclusion:** This statement is **incorrect**.

3. **Evaluate the third statement: "Aerobes can grow in the absence of oxygen."**
- **Analysis:** Aerobes are organisms that require oxygen for their survival. They cannot grow in environments that lack oxygen.
- **Conclusion:** This statement is **incorrect**.

4. **Evaluate the fourth statement: "Obligate anaerobes can live in the presence of abundant oxygen."**
- **Analysis:** Obligate anaerobes are organisms that cannot survive in the presence of oxygen. They require an oxygen-free environment for their growth.
- **Conclusion:** This statement is **incorrect**.

### Final Answer:
The only correct statement is:
- **First statement:** "Anaerobes grow in absence of oxygen."
