Correct Option: D,E

AI Explanation

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

Option A) 5 6 7 - This option is incorrect because it suggests that the code will successfully compile and print the values of variables a, b, and c. However, the code will not compile due to errors.

Option B) 5 followed by an exception - This option is incorrect because it suggests that the code will compile successfully and print the value of variable a, followed by an exception. However, the code will not compile due to errors.

Option C) Compilation fails with an error on line 7 - This option is incorrect because line 7 does not contain any syntax errors. The error occurs later in the code.

Option D) Compilation fails with an error on line 8 - This option is correct. The code fails to compile on line 8 because the class Foo is in a different package (pkgA) than the class Baz (pkgB). Even though the import statement is present on line 4, the protected variable b is not accessible outside of the package.

Option E) Compilation fails with an error on line 9 - This option is correct. The code fails to compile on line 9 because the protected variable b is not accessible outside of the package, even with the import statement. Protected variables can only be accessed by subclasses or classes in the same package.

Option F) Compilation fails with an error on line 10 - This option is incorrect because the variable c is declared as public and can be accessed from any package. Therefore, there will be no compilation error on line 10.

The correct answer is D,E. The code fails to compile with errors on line 8 and line 9.
