For a fixed supply voltage, increasing circuit resistance will

Explanation:
With a fixed supply voltage, the current in a circuit follows I = V/R. Since the voltage V stays the same, increasing the resistance R makes the fraction V/R smaller, so the current decreases. This is also why power drawn from the source, P = VI = V^2/R, falls as resistance goes up. So higher resistance reduces the flow of current; the other possibilities would require changing the voltage or the resistance in a way that doesn’t happen when only resistance is increased.
