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.

Based on the given options, option B is the best example of a citation reference for a work by one author. Here's why:

a. Marks 1999: This option lacks any specific citation format or punctuation, making it less credible as a citation reference.

b. (Marks, Bill. 1999): Although this option includes the author's name and the year of publication, it incorrectly suggests that the author's name is "Marks, Bill," which implies multiple authors rather than just one.

c. (Marks-1999): This option uses a hyphen rather than a comma to separate the author's name from the publication year, which is not the standard format for citation references.

d. Marks et al. 1999: This option includes "et al." after the author's name, which is typically used when there are multiple authors. In this case, since the question explicitly asks for a work by one author, this option does not fit the criteria.

Therefore, none of the above options are correct. It seems that the correct option is missing from the given choices, or there may be some other formatting issues. It would be best to double-check the citation guidelines recommended by your instructor or refer to a reliable style guide (such as APA, MLA, or Chicago) for accurate citation formats.
