In JavaFX, “TextField” is one of the primary controls that contain a rectangular space that gets the input from the programmer or user with the help of a keyboard.
Hence, the correct answer is option “D”.

Explanation of Solution
TextField:
- In JavaFX, “TextField” is one of the primary controls that contain a rectangular space that gets the input from the programmer or user with the help of a keyboard.
- It is also possible to get the text that is entered by the user and use that text anywhere in that program.
- The “TextField” class is used in order to create a “TextField” control. This class is in the package known as “javafx.scene.control”.
Explanation for wrong answers:
Button: Button is not the primary control that is used to display a text. It is used to create an action at the time of clicking a button.
Hence, the option “A” is wrong.
Label: Label is used to display the permanent text and it is not the primary control to display the text.
Hence, the option “B” is wrong.
Message: Message is the sentence or a string and it is not a control.
Hence, the option “C” is wrong.
