  import default.*; 
  class Main { 
      default.MyClass eJava; 
   } 

  None of the above

Note

A class that isn't defined in a package gets implicitly defined in Java's default package.

But such classes can't be accessed by classes or interfaces, which are explicitly defined in a package.

Option a is incorrect.

The MyClass class isn't defined in a package, so it can't be accessed by the Main class, which is defined in the java.oca.associate package.

Options b, c, and d won't compile.

Option b uses invalid syntax in the import statement.

Options c and d try to import classes from nonexistent packages-java.
