Select correct answers from the choices A, B, C, D which are given. Write down only the letter corresponding to the correct answer.
The oxide which reacts with both acid and base is called

Options

A. acidic
B. basic
C. amphoteric
D. neutral

Answer

To solve the question, we need to identify the type of oxide that can react with both acids and bases. Let's break down the solution step by step:

### Step 1: Understand the Types of Oxides
There are different types of oxides based on their reactivity with acids and bases:
- **Acidic Oxides**: These react with bases but not with acids.
- **Basic Oxides**: These react with acids but not with bases.
- **Amphoteric Oxides**: These can react with both acids and bases.
- **Neutral Oxides**: These do not react with either acids or bases.

### Step 2: Analyze the Options
We have the following options:
- A) Acidic
- B) Basic
- C) Amphoteric
- D) Neutral

### Step 3: Evaluate Each Option
- **Option A (Acidic)**: Acidic oxides do not react with bases, so this option is incorrect.
- **Option B (Basic)**: Basic oxides do not react with acids, so this option is also incorrect.
- **Option C (Amphoteric)**: Amphoteric oxides can react with both acids and bases, which fits the definition we are looking for.
- **Option D (Neutral)**: Neutral oxides do not react with either acids or bases, so this option is incorrect.

### Step 4: Conclusion
The correct answer is **C) Amphoteric**, as these oxides can react with both acids and bases.

### Final Answer
C
