Which action will automatically cause Blockers to be unable to block, leading to a penalty?

The action that will lead to Blockers being unable to block and cause a penalty is the concept of "Destroying the Pack." In roller derby, a pack is defined as a group of blockers that work together to impede the opposing team's jammer. When the pack is broken up or "destroyed," it disrupts the gameplay and strategic positioning, leading to penalties being assessed.

When blockers skate out of bounds to avoid a hit, they are also breaking the rules, as it is considered illegal to avoid contact in such a way. Staying outside the Engagement Zone for an extended period may result in blockers being penalized as well, since they are not participating in the game as required.

However, all of these actions contribute to violating the rules that govern blocking, thus making the option that states "All of the above" the complete and correct choice. Each of these actions has specific implications in gameplay and often leads to a penalty situation that hinders a team's ability to defend against the opposing jammer.
