Sorry, but the answer D is incorrect. The correct answer that made the ongoing civil war in Syria even more complicated in 2014 is B. The Assad government used chemical weapons.

To check your answer, let's go through the options and see which one is correct.

A. The Arab Spring led to demonstrations in Syria.
The Arab Spring did indeed lead to demonstrations in Syria, but it doesn't make the ongoing civil war in Syria even more complicated. So this option is not the correct answer.

B. The Assad government used chemical weapons.
The Assad government did use chemical weapons in the ongoing civil war in Syria, but this event occurred before 2014. It doesn't answer the question of what happened in 2014, so this option is not the correct answer.

C. ISIS launched an attack on Syria.
ISIS did play a significant role in the Syrian conflict, but it was in 2013 that they launched a major offensive in Syria, not in 2014. So this option is also not the correct answer.

D. The United States attacked a Syrian air base.
Yes, in 2014, the United States launched airstrikes against an ISIS stronghold in Syria, which was a significant event that made the ongoing civil war in Syria even more complicated. Therefore, the correct answer is D. The United States attacked a Syrian air base.

Your answer appears to be correct!
