Two arguments are often just different opinions about a controversial issue. This is the right option.
An argument may include the reasons why a person holds a certain opinion about an issue or a topic. When two arguments are put together, a debate can be held. This idea is generally present is argumentative conversations or essays. These need to have opposing opinions to construct the argumentative or debatable tone. This is why they always deal with controversial matters.
These options are not right:
-An argument is just people yelling at each other. ( When people have an argument, they generally do so in a heated manner but not always).
-You cannot be good at an argument unless you are yelling. ( You are good at an argument as long as you can develop your reasons to back it up).
- Every argument has a right or wrong point. ( Arguments should not be categorised in this way. An argument should be logically developed).
