Selected Answer: ADG

The three statements that cause a compiler error when inserted at line 1 are: A. int i = theInstance.three++;, D. int a = one++;, and G. int e = ExampleInterface.two++;. These statements cause errors because they attempt to increment final variables, which is not allowed in Java.

ADG all variables declared within an interface are implicitly considered as public, static, and final. This means that interface variables are constants and cannot be modified once they are assigned a value.
