An event is something that happens or occurs within or outside an organisation or project that triggers or affects an activity or process. Events can be classified into three types: external, internal and time-based. Therefore, option B is the correct answer, as it correctly classifies the events of interest in this scenario according to their types. External events are events that originate from outside the organisation or project and are beyond its control or influence. An example of an external event in this scenario is customers ordering through the website, as it originates from outside TeamClothing and is beyond its control or influence. There are two external events in this scenario. Internal events are events that originate from within the organisation or project and are under its control or influence. An example of an internal event in this scenario is shop sales assistants ordering items for a customer online, as it originates from within TeamClothing and is under its control or influence. There are no internal events in this scenario. Time-based events are events that occur at regular intervals or on specific dates or times. An example of a time-based event in this scenario is sending a monthly catalogue to website customers, as it occurs at regular intervals (every month). There is one time-based event in this scenario.
