An automated logistics controller manages the dispatch of delivery vehicles using the algorithm shown below.

1      packages ← GET_PENDING_COUNT()
2      dispatch_limit ← 8
3      WHILE packages > 0 AND dispatch_limit > 0
4          IF packages >= 3 THEN
5              DISPATCH_CARRIER('Truck')
6              packages ← packages - 3
7          ELSE
8              DISPATCH_CARRIER('Van')
9              packages ← packages - 1
10         ENDIF
11         dispatch_limit ← dispatch_limit - 1
12     ENDWHILE

Select the option which shows the line number where iteration is first used in this algorithm.
