Explanation
According to the B2B Commerce Developer Guide, the Order List Component (Aura) for B2B stores displays a list of orders that the user can view and reorder. The component filters the orders based on the current storefront and the current effective account. The current effective account is the account that the user is currently acting on behalf of, which can be different from the user's own account. The component does not show orders placed in other storefronts or related to other accounts, even if the user has access to them.
Therefore, the correct answer is A. Orders placed in the current storefront and related to the current effective account. The other options are incorrect because they do not match the criteria of the component. References: B2B Commerce Developer Guide, Show the Order List Widget
