II With carbon dioxide ,they from salt and water .
(III) The gas evolved with zinc metal extinguishes a lightning splinter .

Options

A. Statements (I) and (III) are correct
B. Only Statements (I) is correct
C. Statements (I) and (II) are correct
D. Only statement (II) correct

Explanation

To solve the question regarding the statements about bases, we will evaluate each statement one by one.

### Step-by-Step Solution:

**Step 1: Analyze Statement I**
- Statement I: "Bases have bitter taste and soapy touch."
- **Evaluation**: This statement is correct. Bases are known for their characteristic bitter taste and slippery or soapy feel when touched.

**Step 2: Analyze Statement II**
- Statement II: "With carbon dioxide, they form salt and water."
- **Evaluation**: This statement is also correct. When a base reacts with an acid (and carbon dioxide is acidic), they typically produce salt and water.

**Step 3: Analyze Statement III**
- Statement III: "The gas evolved with zinc metal extinguishes a lighting splinter."
- **Evaluation**: This statement is incorrect. When zinc reacts with a base (like sodium hydroxide), it produces hydrogen gas. Hydrogen gas is flammable and can actually enhance a flame rather than extinguish it.

### Conclusion:
- Based on the evaluations:
- Statement I is correct.
- Statement II is correct.
- Statement III is incorrect.

Thus, the correct statements are I and II.

### Final Answer:
The correct statements are I and II.
