What is the most likely reason that the Apostle Paul specifically commended Phoebe to the church in Rome (Romans 16:1-2), calling her a 'deaconess' and 'helper'?

A Paul was attempting to establish a separate, female-only church in Rome. B Phoebe was likely the individual delivering Paul's letter to Rome, and his commendation served as a letter of introduction, vouching for her character and trustworthiness as his emissary to ensure the letter was received and understood correctly. C Phoebe was wealthy and Paul wanted to ensure she would continue to financially support his ministry. D Paul was attempting to undermine the authority of the male leaders in the Roman church.
