A) Predecessor of successor of 2000 is 2000.
B) Predecessor of predecessor of 2000 is 1999.
C) Successor of predecessor of 2000 is 2001.
D) Successor of predecessor of 2000 is 2002.

### Step-by-Step Solution:

**Step 1: Analyze Option A**
- **Successor of 2000**: The successor of a number is the number that comes immediately after it. Therefore, the successor of 2000 is **2001**.
- **Predecessor of 2001**: The predecessor of a number is the number that comes immediately before it. Thus, the predecessor of 2001 is **2000**.
- **Conclusion for Option A**: Predecessor of successor of 2000 is indeed **2000**.
**Option A is correct.**

**Step 2: Analyze Option B**
- **Predecessor of 2000**: The predecessor of 2000 is **1999**.
- **Predecessor of 1999**: The predecessor of 1999 is **1998**.
- **Conclusion for Option B**: Predecessor of predecessor of 2000 is **1998**, not 1999.
**Option B is incorrect.**

**Step 3: Analyze Option C**
- **Predecessor of 2000**: As established, the predecessor of 2000 is **1999**.
- **Successor of 1999**: The successor of 1999 is **2000**.
- **Conclusion for Option C**: Successor of predecessor of 2000 is **2000**, not 2001.
**Option C is incorrect.**

**Step 4: Analyze Option D**
- **Predecessor of 2000**: Again, the predecessor of 2000 is **1999**.
- **Successor of 1999**: The successor of 1999 is **2000**.
- **Conclusion for Option D**: Successor of predecessor of 2000 is **2000**, not 2002.
**Option D is incorrect.**

### Final Conclusion:
The only correct option is **A**: Predecessor of successor of 2000 is 2000.
