Which of the following is an example of public dissent?

Public dissent refers to the expression of disagreement or opposition to official policies or actions, typically aimed at influencing change within a society or government. Protesting against government policy is a direct form of public dissent as it involves individuals or groups publicly demonstrating their discontent with government decisions, laws, or practices. This act not only highlights the dissenters' views but also engages the broader community in discussions about important social and political issues, potentially prompting responses from the government or society.

In contrast, voting in elections is primarily a mechanism for participating in the democratic process rather than expressing dissent. Signing a government petition can also signify disagreement but is more of a formal request for action rather than an active demonstration of dissent. Working as a public servant generally indicates support for existing government structures and policies, rather than opposing them. Therefore, protesting is the clearest illustration of public dissent, as it actively seeks to challenge or change governmental actions or policies through visible and often collective displays of opposition.
