Correct Answer

C. The commuter purchases a ticket, checks the timetable, validates the ticket, and then boards the tram.

Explanation

Sequence C follows the logical order of events for a commuter using the tram system detailed in the use case diagram shown here.

The commuter would first need to purchase a ticket to travel. Secondly, after obtaining a ticket, s/he would check the timetable to determine when to travel. Thirdly, before boarding, s/he must validate the ticket at a gate or show it to a ticket inspector. Lastly, the traveller will board the tram.

The alternative sequences either describe steps that are out of sequence or include actions (like reporting a lost card or recharging a card) that are not necessary for a single trip.
