It is useful when you don't have a contact name (sender's name) because it doesn't require an opening (or closing) salutation. There is no opening salutation or complimentary closing, and nothing is indented.
The appropriate salutation depends on whether you also are a solicitor in your own country. If you are a female attorney too, then the appropriate salutation is "Chère Consoeur". However most French lawyers use the "Cher Confrère" salutation regardless of the gender of their interlocutor. If you are a man, you can write "Cher Confrère". If you are not an attorney, then the appropriate salutation always is 'Cher Maitre' or simply "Maître".
the answer is A. Salutation

Note
The complimentary closing should go at the end of the letter in an informal letter.
comma
Using a colon in the salutation and a comma in closing.
A comma should follow the closing if there is a colon following the salutation.
