以下哪項探索技巧可讓你以圖表呈現使用者完成某件要務或重要轉換前採取的步驟，並確定他們完成或不完成各個步驟的情況？

Funnel exploration is the correct answer because it is specifically designed to visualize the steps users take toward a conversion and identify where they drop off. This technique allows you to define a series of sequential steps and see how many users complete each step, providing insights into user behavior and potential friction points in the conversion path. Segment overlap helps identify commonalities between different user segments but doesn't visualize sequential steps. Free-form reports offer flexible data visualization but lack the specific step-by-step analysis of a funnel. Cohort exploration analyzes user behavior over time based on a shared characteristic, which is different from tracking a conversion path.
