price = 4; /* Line 5 */
} /* Line 6 */
} /* Line 7 */

What will make this code compile and run?

A.
Change line 2 to the following:
Public int price

B.
Change line 4 to the following:
int price = new Simple ();

C.
Change line 4 to the following:
Float price = new Simple ();

D.
Change line 5 to the following:
price = 4f;

E.
Change line 5 to the following:
price.price = 4;

F.

G.

price.price =4; is correct, not price=4;
The attribute price of the instance must be set, not the instance itself.
