Correct Answer: For an argument both parties are equally responsible

Solution : The third option is correct.

The idiom it takes two to tango is often used to convey that conflicts or problems generally arise from the actions or contributions of all involved parties.

It emphasises the idea that a collaborative effort or interaction is required for a situation to occur.

In the context of an argument, it implies that both individuals have a role in the dispute, and it's not solely the fault of one person.

Therefore, the correct answer will be: "For an argument both parties are equally responsible."
