Final answer:
President Zelenskyy would most likely agree with the statement that the Ukrainian democratic government has angered Putin, supported by Putin's direct threats to pro-democracy activists after the 2014 revolution.
Step-by-step explanation:
President Volodymyr Zelenskyy would most likely agree with answer choice (C), "Ukraine's democratic government has angered Putin for many years." The supporting sentence from the article is, "Putin directly threatened pro-democracy activists and government officials who had led the pro-democracy push in the country after the 2014 revolution ousting a pro-Russian government." This statement best aligns with Zelenskyy's stance given his advocacy for a Ukrainian democracy and resistance against Russian aggression.
