The upper classes lost much of their power and thus revolted.
Explanation:
This is the answer that best fits with the context of Western imperialism in South Asia. When imperialism began to take root in South Asia, the most prevalent reaction was one of resistance. The upper classes were dominant in the region, and they did not want to lose their power and control. They revolted, but in general, they were unable to overcome the Western powers.
The first response was often to attempt to drive out the invading Western armies. The superior technology that the West employed often made these fights extremely deadly for the native people. From that point then it was more about preserving the native culture. Many nations and peoples would also slowly accept the liberal ideals that the West brought.
The best answer for initial response is that of rebellion often by the wealthy. They had the most to lose in wealth, power, and control.
