D Correct answer
Explanation

Calling r.get() prints Root. Calling t.get() and t1.get() invokes the overridden get() method in Tree, printing Tree and setting bark to 15. Since bark is inherited from Root and not shadowed in Tree, t.bark and t1.bark both print 15, while r.bark remains 10 as it was never modified.
