Concept:The question tests knowledge of British colonial policies and events in India during the 1870s and 1880s. The incorrect statement concerns the Vernacular Press Act.
Explanation:The Arms Act was passed in 1878 and disallowed Indians from possessing arms. This is correct.
The Vernacular Press Act was actually passed in 1878, not 1880. Its aim was to curb criticism from the Indian-language press, not to support the government. So option B is false.
In 1883, the Ilbert Bill caused a major controversy because it proposed allowing Indian judges to try British subjects. This statement is correct.
Dissatisfaction with British rule did intensify in the 1870s and 1880s due to repressive laws and racial discrimination. This statement is correct.
Therefore, only option B contains an error.
Answer:Option B is incorrect.
