What phrase can describe Robert's reaction to being excluded from the team?

The phrase "Robert took exception to being left out" effectively captures a negative reaction that indicates displeasure or dissatisfaction with his exclusion from the team. This choice highlights that Robert felt a sense of injustice or offense about not being included, which aligns with a common emotional response to being excluded from a group or activity.

The other choices suggest a neutral or positive acceptance of exclusion, which does not reflect an emotional reaction typically associated with feeling left out. For instance, accepting exclusion or feeling grateful or even enjoying it conflicts with the more likely human reaction of disappointment or upset in such situations. In summary, the first option accurately represents a strong emotional response that one would expect when someone feels wronged by being left out.
