Solution

The purpose of the second argument in the useEffect Hook is B: To specify the dependencies of the effect. This argument is an array where you can list the state and props values that the effect depends on. If these values change between renders, the effect will run again. If you pass an empty array ([]), the effect will only run once after the initial render, similar to componentDidMount in class components.
