The most accurate critique of presidential systems of government from the options provided is: "Presidential systems of government are more likely to result in a high concentration of power in a single branch."
In many presidential systems, the president has significant authority and independence from the legislature, which can result in a concentration of power within the executive branch. While there are checks and balances in place (including judicial review), the potential for the president to wield substantial power is a point of critique often discussed in political science.
The other statements either mischaracterize how presidential systems function (such as the idea that courts cannot stop presidential actions) or are more descriptive rather than critical of the system itself (like the statement about divided government). The last statement incorrectly describes the nature of presidential systems, as they typically involve direct election of the executive rather than selection by the legislature.
