AI Explanation

To answer this question, let's go through each option to understand why it is correct or incorrect:

Option A) Compilation fails with an error at line 4 - This option is incorrect. The code at line 4 is valid and will not cause a compilation error.

Option B) Compilation fails with an error at line 3 - This option is incorrect. The code at line 3 is valid and will not cause a compilation error.

Option C) true - This option is correct. The code at line 4 checks whether the variable "index" is an instance of the Object class. Since arrays in Java are objects, the expression "index instanceof Object" evaluates to true.

Option D) false - This option is incorrect. As mentioned earlier, arrays in Java are objects, so the expression "index instanceof Object" evaluates to true, not false.

The correct answer is C) true. This option is correct because the code will output "true" to the console.
