Final answer:
Option (c), Many Russians disliked Nicholas II due to Russia's defeat by Japan, his indecisive leadership, and his ineffective handling of WWI, leading to his abdication in the 1917 Revolution.
Step-by-step explanation:
One reason many Russian people did not like Tsar Nicholas II was Russia's defeat by Japan in the Russo-Japanese War, which led to a national crisis and demonstrated Nicholas II's indecisive leadership. Additionally, the harsh response to peaceful protesters and the subsequent violent suppression of the Revolution of 1905 further fueled discontent.
Furthermore, Nicholas II's handling of World War I, with massive casualties, shortages, and overall incompetence, along with the lack of government responses to internal strife, food shortages, and the oppression of rights, led to his downfall and subsequent abdication during the Russian Revolution of 1917.
