The given answer (Option D: 00 01 10 11) is incorrect.
Let’s evaluate the nested loops:
Outer loop: i runs from 0 to 2
Inner loop: j runs from 0 to 1
Execution order:
i = 0
j = 0 → prints 00
j = 1 → prints 01
i = 1
j = 0 → prints 10
j = 1 → prints 11
i = 2
j = 0 → prints 20
j = 1 → prints 21
Final output:
00 01 10 11 20 21
Since none of the given options match this output, the correct answer is not listed.
