❌ A. 10 ✅ B. 15 ❌ C. 25 ❌ D. Compiler error on line 3. ❌ E. Compiler error on line 8. ❌ F. None of the above.
Explanation: The code compiles successfully, so options D and E are incorrect. The value of a cannot be changed by the addToInt method, no matter what the method does, because only a copy of the variable is passed into the parameter x. Therefore, a does not change and the output on line 9 is 15.
