Wait, are we sure the object is being deleted properly? If there's a memory leak, it might print some random value like 1 or 0.

I believe the answer is A) It prints: 5 because the object is initialized with 5.

Hmm, I'm not so sure. What if the compiler optimizes the code and the object ends up being created with the default constructor instead of the one that takes an argument? Then it would print 10.

The code will print 5, as we create a BaseC object with the constructor that takes an integer argument and pass in the value 5.
