Why is the use of a.c. voltatage preferred over d.c. voltage? give two reasons

Use of a.c. voltage is preferred over d.c. voltage on account of the following reasons:
(i) An a.c generator is easy to operate and maintain. So we prefer to use a.c. voltage.
(ii) Using a Transformer voltage of a.c supply may be suitably increased or decreased.
(iii) a.c. power may be transmitted over long distances without much loss of energy.
