Question 9

An algorithm is designed to monitor a chemical reaction temperature and update its hazard status. The pseudocode is shown below:

1      temp ← USERINPUT
2      duration ← USERINPUT
3      threshold ← 80.0
4      status ← "normal"
5      WHILE temp > threshold DO
6          status ← "alert"
7          IF duration > 15 THEN
8              status ← "critical"
9          ENDIF
10         temp ← temp - 5.0
11     ENDWHILE
12     OUTPUT status

Select the option that shows the line number where selection is first used in this algorithm.
