The method that creates a new array populated with the elements of array that return a value of true from the callback function is the array.filter() method. This method iterates over each element in the array and checks if the callback function returns true for that element. If it does, then that element is added to the new array that is returned by the method. Therefore, the best choice for this question is option B, array.filter().
