which of the following statement is correct?

Options

A. cathode is -ve terminal in both ,galvanic and electrolytic cells
B. Anode is +ve terminal in both,galvanic and electrolytic cells
C. cathode and anode are -ve terminal in electrolytic and galvanic cell respectively.
D. Cathode and anode are +ve terminal in electroytic and galvanic cell respectively.

Answer

To determine which statement is correct regarding the anode and cathode in galvanic and electrolytic cells, we need to understand the definitions and roles of these components in both types of cells.

### Step-by-Step Solution:

1. **Understand the Definitions**:
- **Galvanic Cell**: A type of electrochemical cell that generates electrical energy from spontaneous chemical reactions. In this cell, the anode is where oxidation occurs and is the negative terminal, while the cathode is where reduction occurs and is the positive terminal.
- **Electrolytic Cell**: A type of electrochemical cell that uses electrical energy to drive a non-spontaneous chemical reaction. In this cell, the anode is where oxidation occurs and is the positive terminal, while the cathode is where reduction occurs and is the negative terminal.

2. **Analyze the Statements**:
- **Statement 1**: "Anode is negative terminal in both galvanic and electrolytic cell."
- This is incorrect because the anode is positive in an electrolytic cell.
- **Statement 2**: "Anode is positive terminal in both cells."
- This is incorrect because the anode is negative in a galvanic cell.
- **Statement 3**: "Cathode and anode are negative terminal in electrolytic and galvanic cell respectively."
- This is incorrect because the cathode is negative in an electrolytic cell, but the anode is negative in a galvanic cell, making the statement contradictory.
- **Statement 4**: "Cathode and anode are positive terminal in electrolytic and galvanic cell respectively."
- This is incorrect since the cathode in an electrolytic cell is negative, and the anode in a galvanic cell is negative.

3. **Identify the Correct Answer**:
- After analyzing all statements, none of the provided statements are correct. However, if we were to rephrase the understanding:
- In a **galvanic cell**, the anode is negative and the cathode is positive.
- In an **electrolytic cell**, the anode is positive and the cathode is negative.

### Conclusion:
None of the statements provided in the question are correct based on the definitions and roles of anodes and cathodes in galvanic and electrolytic cells.
