Step-by-Step Solution

Solution:

Step 1: Trace the loop iterations
Start with i=1, print i, then increment i. Loop continues while i <= 3.
Step 2: List printed values
Values printed are 1, 2, and 3. When i becomes 4, condition fails and loop stops.
Final Answer:
1 2 3 -> Option D
Quick Check:
Loop prints 1 to 3 inclusive [OK]

Quick Trick: do-while runs body before condition check [OK]
