The correct answer is A) Imprisonment of political dissidents rarely ends opposition to the government.
The conclusion that is best supported by this cartoon is "Imprisonment of political dissidents rarely ends opposition to the government."
This has been shown in many civil rights movements around the world. The government thinks that putting in jail the heads of any civil rights movement would be enough to stop the movement or a revolt. But in most cases, this is not the truth. On the contrary, when the leader is jailed, automatically it becomes a martyr, and its followers have a stronger reason to fight for. This was the case of Nelson Mandela and the South African people. After so many years in prison, Mandela left jail to become the President of South Africa.
