The correct answer should be The voters cast their ballots in a building called Independence Hall but they were not free to make their own decisions.
Explanation:
Although ballots were cast at the independence hall by delegates to the congress, the delegates were not free to make their own decisions. This was because delegates were elected to the Congress by thirteen different governments, and these delegates were bound by whatever instructions were given to them. For this reason, regardless of their personal opinions, the delegates could not vote for or against independence unless their instructions permitted such an action. This is an irony because the congress voted for independence, being bound by the instructions given to them.
