Which phrase can be used to sum up or conclude an argument?
a. as a result
b. as an example
c. compared to
d. in addition

Letter A is the correct option.

Explanation:

In this case, the word "result" could be understood as a synonym for "conclusion", both indicating the end of an argument. Letters B, C, and D, can be used while developing the idea because those phrases are very useful when trying to explain something. They all have the same intention (comparing or adding information); due to that, their main purpose is not to close an argument but to keep incorporating things.
