Assertion : `OH^-` can behave as amphoteric.
Reason : It can accept and donate `H^+`.

Options

A. Assertion and reason both are correct statements and Reason is correct explanation for assertion.
B. Assertion and reason both are correct statement but reason is not correct explanation for assertion
C. Assertion is correct statement but reason is wrong statement.
D. Assertion is wrong statement but reason is correct statement

Answer

To analyze the assertion and reason provided in the question, we can break it down step by step:

### Step 1: Understanding the Assertion
The assertion states that `OH^-` (hydroxide ion) can behave as amphoteric.

**Explanation:**
An amphoteric substance is one that can act as both an acid and a base. In this case, `OH^-` can indeed act as an amphoteric species.

### Step 2: Understanding the Reason
The reason given is that `OH^-` can accept and donate `H^+` (proton).

**Explanation:**
- As a base, `OH^-` can accept a proton (`H^+`) to form water (`H2O`):
\[ OH^- + H^+ \rightarrow H2O \]
- As an acid, `OH^-` can donate a proton to form oxide ion (`O^{2-}`):
\[ OH^- \rightarrow O^{2-} + H^+ \]

### Step 3: Conclusion
Since `OH^-` can both accept and donate protons, it confirms that it is indeed amphoteric. Therefore, both the assertion and reason are true, and the reason correctly explains the assertion.

### Final Answer
Both the assertion and reason are true, and the reason correctly explains the assertion.
