How should the team’s improvement in scores be accurately described for pronoun use?

The correct choice, which states, "The team achieved a 38% improvement in its scores," effectively illustrates proper pronoun use in relation to collective nouns. In this context, "team" is treated as a singular collective noun, indicating that the group is acting as a single entity. The use of "its" reflects this singular perspective accurately, denoting that the improvement in scores pertains to the team as a whole.

This choice also clearly communicates the extent of improvement, specifying the percentage, which adds a quantitative measure to the statement. The phrasing removes ambiguity, ensuring that readers understand the improvement is not related to individual scores but rather to the collective performance of the team.

In contrast, the other options may create confusion or lack clarity about the focus on the team as a singular unit.
