Correct Answer: talked

Solution : The third option is correct.

In the given sentence, the phrase spoke about indicates a conversation or discussion on the topic of political unrest within the state.

Among the options provided:

• Expressed : This term denotes conveying thoughts or feelings but doesn't specifically imply a conversation or discussion.
• Said : While it refers to verbal expression, it's a bit generic and doesn't specifically suggest a conversation or discussion involving multiple individuals.
• Talked : This word best fits the context as it signifies a conversation or discussion among people about the political turmoil.
• Stated: It implies expressing something definitively or explicitly but doesn't strongly convey a conversation or discussion.

Therefore, the correct sentence is: They talked about the political turmoil in the state.
