To make a JTextField editable or non-editable, you use:

setEditable()
setTextFieldType()
enableEditing()
toggleEditable()

The correct answer is: setEditable()

To make a JTextField editable or non-editable, you use the method setEditable(). This method specifically changes the 'editable' property of the JTextField and allows the user to input or change the text. Choices B, C, and D are all incorrect because those methods do not exist and do not offer the functionality to make a JTextField editable/non-editable. Choice B is especially incorrect because there is no method called setTextFieldType() in Java.
