Question

the supreme court can strike down, or cancel, laws that go against the constitution. which arrow stands for this check?

Explanation:

The Supreme Court (Judicial branch) checking laws from the Legislative branch (which makes laws) for constitutionality is represented by the arrow from Judicial to Legislative. This is part of the system of checks and balances, where the Judicial branch can declare Legislative laws unconstitutional. So the arrow going from the "Judicial" circle to the "Legislative" circle (the one where Judicial points to Legislative) represents this check.

Answer:

The arrow from the "Judicial" circle to the "Legislative" circle (the arrow where the Judicial branch points toward the Legislative branch).
