Incomplete question. The options read;

- Leader-member exchange theory
- Vigilant interaction theory
- Expectancy theory
Answer:
Vigilant interaction theory
Step-by-step explanation:
Remember, we are told that Alexa and David kept a running total of who is winning on a whiteboard for the entire team to see while also strategizing ways to beat the opposing team.
According to the vigilant interaction theory, the productivity of a team is usually dependent upon the group's attentiveness during their group interaction.
Hence, we can thus conclude that Alexa and David are employing vigilant interaction theory to increase productivity.
