Step-by-Step Solution

Solution:

Step 1: Analyze the loop condition and variable
The loop runs until count > 3. Starting from 1, it prints and increments count.
Step 2: Trace each iteration
Prints 1, increments to 2; prints 2, increments to 3; prints 3, increments to 4; now count > 3, loop stops.
Final Answer:
1 2 3 -> Option B
Quick Check:
Prints 1 to 3 before stopping [OK]

Quick Trick: Until runs while condition false, stops when count > 3 [OK]
