In Catch-22, The Great Loyalty Oath Crusade is one example of

The need to show true patriotism in war.
The importance of being able to trust companions.
The ability of spies to remain hidden despite careful efforts to unmask them.
The desire of officers to gain publicity.

I am stuck between A and D.

It's probably A then right? I was leaning more towards A anyway, but I just wanted to make sure.

D. The whole novel is satirizing not only war, but the internal politics and the true nature of relationships and personal desires and the hidden agendas of people. Nearly every sentence in the novel has a reciprocal sentence with an ironic twist or invalidated the previous one. "He is, then he isn't." "A is true but B is truer." It's been a long time since I've read the novel but it stands still as a favorite and it strikes me as touched by genius in every word. The more absurd it gets, the closer to the truth Heller comes. The irony and humor of asking a person who's already in a position of getting killed for his nation to sign a loyalty oath to pass the salt seems too obvious and makes me wonder if the OP of the question is just baiting for the fun of it.

To determine the correct answer between options A and D, we need to analyze the context of "The Great Loyalty Oath Crusade" in Catch-22.

In the novel, "The Great Loyalty Oath Crusade" refers to a bureaucratic initiative in which the officers of the U.S. Army Air Forces were required to sign loyalty oaths to demonstrate their patriotism and loyalty to their country. This requirement was fueled by the desire of officers to gain publicity and make their actions appear more patriotic. The campaign was a way for the officers to be seen as supporting the war effort and to improve their image.

Therefore, the correct answer is option D: The desire of officers to gain publicity. "The Great Loyalty Oath Crusade" exemplifies this particular motivation rather than the need to show true patriotism in war, as described in option A.
