Evaluation of argument clarity in essay writing primarily hinges on the presentation of a logical sequence of ideas. A well-structured essay allows the reader to easily follow the writer's thought process, effectively conveying the argument being made. Clear logical progression ensures that each point builds upon the previous one, creating a coherent narrative that reinforces the overall thesis. This clarity enables the reader to understand the connections between various arguments and insights, which is essential for effective communication in academic writing.

In contrast, text length does not inherently indicate clarity, as longer essays can still lack focus. The number of complex sentences is not a direct measure of clarity either; more complex sentences can lead to confusion if not used judiciously. Lastly, informal expressions typically detract from academic clarity, as they may introduce ambiguity or an overly casual tone that does not suit formal writing contexts. Thus, the correct choice emphasizes the importance of logical structure in crafting clear and effective arguments.
