Option A is not correct because in boolean data type it's consists only true or false statement.
Option B also not correct because false is declared within single quotes like string.
So, Option C is right.

For the option D we can initialize a boolean with this method.
Boolean b = Boolean.FALSE;
Boolean b = Boolean.TRUE;
Boolean b = Boolean.FALSE;
Boolean b = Boolean.TRUE;
