Select the correct statement.

Options

A. Faraday represents `96500` coulombs per second.
B. Coulomb represents one ampere for `1//2` second.
C. Coulomb represents `1//2` ampere for 1 second
D. Faraday represents charge of one mole electrone.

Explanation

To solve the question, we need to evaluate each of the given statements regarding Faraday and coulombs.

1. **Understanding Faraday's Constant**:
- Faraday's constant (F) is defined as the amount of electric charge per mole of electrons. It is approximately equal to 96500 coulombs. This means that one mole of electrons carries a charge of about 96500 coulombs.

2. **Evaluating the Statements**:
- **Option A**: "Faraday represents 96500 coulombs per second."
- This statement is incorrect. Faraday's constant represents the total charge per mole of electrons, not a rate of charge per second.

- **Option B**: "Coulomb represents 1 ampere for half a second."
- This statement is also incorrect. A coulomb is defined as the amount of charge transferred by a current of one ampere in one second, not half a second.

- **Option C**: "Coulomb represents half ampere for one second."
- This statement is incorrect as well. A coulomb is the charge transferred by one ampere in one second, not half an ampere.

- **Option D**: "Faraday represents charge of one mole of electron."
- This statement is correct. Faraday's constant indeed represents the charge of one mole of electrons, which is approximately 96500 coulombs.

3. **Conclusion**:
- After evaluating all the options, the only correct statement is **Option D**: "Faraday represents charge of one mole of electron."

### Final Answer:
The correct statement is: **Option D: Faraday represents charge of one mole of electron.**
