Answer: C. 11111
The loop runs for 5 iterations (i = 10, 11, 12, 13, 14), each printing '1' once before the break statement terminates the inner while loop, producing '11111'.
Step-by-step Derivation:
Step 1: The outer for-loop sets i from 10 to 14 (5 iterations).
Step 2: In each iteration, the inner do-while loop executes printf, printing '1'.
Step 3: The continue statement branches to while(0), terminating the do-while loop.
Step 4: The subsequent break statement exits the while(i) loop.
Step 5: Thus exactly 5 ones are printed: '11111'.
