It's funny that I paid for this exam and it turns out it's not entirely accurate. I deserve a refund for correcting all this stuff LOL.

Correct Answer: D (The first flow executes successfully, and the remaining will be skipped.) Support: https://docs.appian.com/suite/help/23.4/XOR_Node.html "A looping flow should not be directed into an XOR gateway itself, but into another upstream activity. For example, place an empty Script Task node between the incoming flows and the XOR node when you are routing multiple flows into the XOR." https://community.appian.com/discussions/f/general/7196/xor-gateway-stuck

Selected Answer: B
According to Appian Documentation (XOR Gateway), when multiple input flows are connected to an XOR gateway, the first flow token through to an exclusive outgoing flow, and subsequent flow tokens wait for all incoming flows to arrive before executing the output flow decision. Therefore, when the second input flow reaches the XOR gateway, it will wait for all the other incoming flows to arrive before the output flow decision is made. So, the answer is B. The first flow executes successfully, and the remaining will wait indefinitely.
