Which sentence does not contain any errors in the use of italics or quotation marks?
*= italics
a.
is the word "statistics" spelled correctly in that paragraph?

b.
use the word an* before a noun that begins with a vowel sound.

c.
how many s's does the state have in its name?

d.
mary's lucky number is "7."

Having in mind that the italics are popularly used to call attention to certain words in a block of text and that some of the rules for quotation are: Use double quotation marks to set off a direct (word-for-word) quotation and Always capitalize the first word in a complete quotation, even midsentence. then the correct one here is the B option. Hope this can help
