Which part of a formal e-mail is optional a the closing b the contact info c the persons last name d the salutation

B) The contact info.

The purpose of an email letter is to convey a message, inform and/or report, and within its structure there are some part necessaries such as the heading, the salutation, the body, the closing and the complete name of the person or company who is sending it, however the author always have the choice to keep private his/her personal and contact information, such as phone number, address, etc. so it can be contacted by email only.

the narrator is a first person, participant one, who describes in the simple past tense important and difficult events in his earlier life. he also provides temporal markers as the month (january) and the time (12: 30 pm). finally the account of his experience is very detailed, to the extent that a participant narrator would talk the same way about his experiences. a good example of such detail is the mention of the “bovril ration” which historically was a native american food adopted by european explorers in arctic and antarctic regions due to its high level of calories.

choices ? or is this a actual question from yourself ?
