Which sentence does not contain any errors in the use of italics or quotation marks?

a. i have never been able to spell the word "occurrence" without looking it up.
b. how many n's does she have in her last name?
c. janet's cell phone number begins with an "8."
d. the word the begins many newspaper articles.

I am pretty sure that the sentence which does not contain any errors in the use of italics or quotation marks is the first one : A.I have never been able to spell the word "occurrence" without looking it up. I choose this one because all the optons besides this one contents error:  How many n's does she have in her last name? --- n should be covered with quotation mark, like that ''n'''s
Janet's cell phone number begins with an "8." There is no need to use them
The word the begins many newspaper articles. ''the'' should look like that.
Hopw that helps!
