Based on the tone of the memo above, which of the following BEST describes Sonja and Gabriela’s relationship?

The tone of the article is one of mutual respect. The writer uses collective pronouns such as “we” and “us” to suggest that the two people are equally invested in this decision. While answer choice "Sonja and Gabriela work in the Human Resources Department together." may also account for this familiarity, it wouldn’t make sense for two people from HR to decide to open a new location.
