Answer:
Concentrated targeting strategy.
Explanation:
Concentrated targeting strategy is one that defines a very specific segment of the consumer population.
Since only one segment is targeted then only one marketing mix is selected to suit the companie's clients. Companies that adopt this strategy focus on analysing the needs of the selected segment and focus all their efforts on meeting their needs.
This gives differential advantage as other companies do not focus all their effort on the segment.
So Penguin Catering Services targeting only events at resorts in its geographic region is a form of concentrated targeting.
