Why was the combination of economic and political aspects in the demands of the February Revolution important?

Correct answer: It brought life crisis and demand for change in rule together

Economic demands concern the conditions in which people live and work. In Petrograd, demands connected with bread, wages, shortages, and relief from hardship expressed the immediate suffering of workers and families. Political demands concerned rights, representation, and a change in the form of government. When these demands came together, the movement challenged both the material causes of dissatisfaction and the political system that people believed was unable or unwilling to solve them.

Option A is correct because it explains this combined character: the life crisis and the demand for a change in rule were connected. The movement was not religious, so B is irrelevant. It did not stabilise Tsarist rule; rather, it weakened that rule, making C wrong. The workers were active in political events, so D reverses the historical meaning. The best interpretation is that the revolution had several connected causes.
