Which of the following is prevented through the expression of different points of view in government? authoritarianism gridlock compromise consensus

I would say that authoritarianism is prevented in this case.
Authoritarianism means that there is only one person deciding what is right or what is wrong, according to their own thoughts and ideas. Nobody else has a say in a such an organization. However, here, that is obviously not the case, which is why that is prevented when a lot of people express their own opinions.
