Option (c) is correct

The fallacy in the above argument is "Undistributed Middle". This is a type of formal fallacy where the middle term in a categorical syllogism is not distributed at least once in the premises. In this argument, the middle term is "against gun control". The premise states that supporters of ABC Political Party are against gun control and Republicans are also against gun control, but it does not distribute the middle term "against gun control" to either group. Therefore, the conclusion that some Republicans must be supporters of ABC Political Party does not logically follow.
