Which of the following code snippets creates a Line and uses a RotateTransition object to animate it for seven seconds?

a. Line myLine = new Line(25, 50, 100, 50);
RotateTransition rtrans =
new RotateTransition(new Duration(7000), myLine);

b. Line myLine = new Line(25, 50, 100, 50);
RotateTransition rtrans =
new RotateTransition(new Duration(7), myLine);

c. Line myLine = new Line(25, 50, 100, 50);
RotateTransition rtrans =
new Duration(7000), myLine;

d. Line myLine = new Line(25, 50);
RotateTransition rtrans =
new RotateTransition(new Duration(7000), Line);

a. Line myLine = new Line(25, 50, 100, 50);
RotateTransition rtrans =
new RotateTransition(new Duration(7000), myLine);
