Bases fumish ......ions in solutions.

Options

A. `H^(+)`
B. `OH^(-)`
C. Both (1) and (2)
D. None of these

Explanation

To solve the question "Bases furnish ......ions in solutions," we need to understand the definition and behavior of bases in aqueous solutions.

### Step-by-Step Solution:

1. **Understanding Bases**:
- A base is a substance that can accept protons (H⁺ ions) or donate hydroxide ions (OH⁻ ions) in a solution.

2. **Identifying the Ions Furnished by Bases**:
- When bases dissolve in water, they dissociate to release hydroxide ions (OH⁻). This is the key characteristic of bases.

3. **Examples of Bases**:
- For instance, sodium hydroxide (NaOH) dissociates in water to produce sodium ions (Na⁺) and hydroxide ions (OH⁻).
- Another example is ammonium hydroxide (NH₄OH), which dissociates to give ammonium ions (NH₄⁺) and hydroxide ions (OH⁻).

4. **Conclusion**:
- Therefore, the correct completion of the statement "Bases furnish ......ions in solutions" is "OH⁻ ions."

### Final Answer:
Bases furnish **OH⁻ ions** in solutions.
