What is meant by the term 'lead jammer'?

The term 'lead jammer' refers to the first jammer to legally pass all opposing blockers while also ensuring they have not committed any penalties during the process. This status is crucial during a jam because the lead jammer can call off the jam at any moment to stop play, allowing them to control the pace of the game and strategize effectively. Achieving lead jammer status gives the team an advantage, as it can help secure points and manage the opposing team's scoring opportunities.

In the context of the other options, while they may describe aspects of jamming or scoring, they do not accurately capture the specific role and implications of being designated as 'lead jammer.' For instance, while leading in points scored might seem relevant, it is not the defining characteristic of a lead jammer. Similarly, saying the only jammer allowed on the track or those who effectively remove blockers does not reflect the criteria and importance of passing the opposing blockers legally to earn that designation. Thus, option C precisely defines what it means to be a lead jammer in roller derby.
