Final answer:
The statement with an error is II) public static void Main(String [] args) as the main method should be written in all lowercase as main. Statements I) and III) are correct and contain no syntax errors.
Step-by-step explanation:
The statement that contains an error among the ones provided is II) public static void Main(String [] args). In Java, the method signature for the main method should be public static void main(String[] args), with 'main' written in all lowercase.
There is no error in statement I) import java.util.Scanner; because it is the correct syntax for importing the Scanner class from the java.util package.
Statement III) Scanner in = new Scanner(System.in); is also correct and is the typical way of creating a new Scanner object to read input from standard input (System.in).
