Step-by-Step Solution
Solution:
Step 1: Understand loop initialization and increment
The loop starts at i=2, runs while i is less than or equal to 6, and increments i by 2 each time.Step 2: List values printed
Values printed are 2, then 4, then 6. After 6, i becomes 8 which breaks the condition.Final Answer:
2 4 6 -> Option DQuick Check:
Increment by 2 from 2 to 6 prints 2,4,6 [OK]
Quick Trick: Check increment step and loop condition carefully [OK]
Common Mistakes:

- Confusing <= with <
