Which of the following is the bst example of a citation reference for a work by one author?

a. Marks 1999
B. (Marks, Bill.1999)
c. (Marks-1999)
d. Marks et.al. 1999
e. none of the above

I know that C and D are wrong
I think A is wrong as it has no punctuation.
for B, I think it is wrong too as there seems to have two authors. one is Marks and one is Bill
So is E (none of the above) correct?
Thanks!

I agree that E is correct.

I agree with Writeacher. According to APA guidelines, none of the above are correct.
