What punctuation or abbreviations are used in an in-text citation?

D. None of these is the answer. In an in-text citation, the authors last name and page number is used, but this is not one of the options. Therefore the correct answer is none of these.

I hope this helped you out :)

i decided to stay late in the laboratory to continue my experiment with the lightbulb. at midnight, thomas edison opened the door and saw all the stuff he was working on. the lightbulb, film and the transmitter. as he walks in an idea hits him on how the lightbulb would work. he would have to change a few wires around to get it to light up. when he did change the wires around it worked so he decided to write a telegraph to his friend to tell him about his success.   as he was packing up he grabbed the telegraph and walked to his home. he told his wife about the success and the next morning mailed the telegraph.
