Select the option that expresses the given sentence in direct speech.

She told the car mechanic that her car was giving very low mileage.

She said to the car mechanic, “My car is giving very low mileage.”

The correct option is: She said to the car mechanic, "My car is giving very low mileage."

The other options are incorrect:

• The car mechanic said to her, “Your car is giving very low mileage.” This is incorrect because the speaker is the one who is talking to the car mechanic.
• She said to the car mechanic, “Her car has been giving very low mileage.” This is incorrect because the speaker is referring to her own car, not someone else's car.
• She asked the car mechanic, “Why is my car giving very low mileage?” This is incorrect because the reported speech is a statement, not a question.
