B. `O_(2)^(2-)gtO_(2)^(-)gtO_2^(+)gtO_(2)`
C. `O_(2)^(+)gtO_(2)gtO_2^(-)gtO_(2)^(2-)`
D. `O_(2)^(2-)gtO_(2)^(-)gtO_2gtO_(2)^(+)`

Explanation

To determine the correct order of bond strength for different forms of oxygen, we need to calculate the bond order for each species. The bond order can be calculated using the formula:

**Bond Order = (Number of Bonding Electrons - Number of Anti-bonding Electrons) / 2**

Let's analyze the different forms of oxygen:

1. **O2 (Dioxygen)**:
- Bonding Electrons: 10
- Anti-bonding Electrons: 6
- Bond Order = (10 - 6) / 2 = 2

2. **O2- (Superoxide)**:
- Bonding Electrons: 10
- Anti-bonding Electrons: 5
- Bond Order = (10 - 5) / 2 = 2.5

3. **O2- (Peroxide)**:
- Bonding Electrons: 8
- Anti-bonding Electrons: 6
- Bond Order = (8 - 6) / 2 = 1

4. **O2+ (Oxygen cation)**:
- Bonding Electrons: 9
- Anti-bonding Electrons: 5
- Bond Order = (9 - 5) / 2 = 2

5. **O2-2 (Dioxygen dianion)**:
- Bonding Electrons: 8
- Anti-bonding Electrons: 8
- Bond Order = (8 - 8) / 2 = 0

Now, let's summarize the bond orders:

- O2+ : 2.5
- O2 : 2
- O2- : 1.5
- O2-2 : 1

### Conclusion:
The order of bond strength based on bond order is:
**O2+ > O2 > O2- > O2-2**
