I think the answer is A.
*Words with the star are italics

What do the parentheses mean in sentences A and D?

Another teacher on the site told me to put the words in parathesis to say that they are in italics as well.

Yes, you are correct. Sentence A is written correctly. Here's why:

In this sentence, the title of the novel, "Gathering Clouds," is correctly formatted using italics. In written English, it is customary to use italics to denote the titles of larger works, such as novels, books, and movies. Additionally, the comma is appropriately placed before the name of the author, Greg Innis, and there is a correct use of future tense by using the phrase "will be signing books here tomorrow." Therefore, sentence A is the correct sentence out of the given options.
