The question offers four options. Books, magazines, and encyclopedia have page numbers so it is mandatory to include them in an in-text citation. On the other hand, internet sources do not have pages because of the format, so it is unnecessary and not possible to include this information, so this is the correct answer.
A plot of a novel is an artificial ordering of events. The correct option among all the options that are given in the question is the third option or option "C". It is actually nothing but a fictitious prose narrative. I hope that this is the answer you were looking for and it has come to your help.
