Select the proper pronoun: "None of the team has stated (his or her, their) position clearly?"

The correct pronoun in this context is "his or her." The phrase "None of the team" is referring to a collective group, which in this instance is considered singular because it emphasizes the team as a single unit. Therefore, using "his or her" respects the singular nature of the subject and maintains proper agreement in terms of number and gender.

Using "their" is a common practice in modern English when referring to singular nouns in a gender-neutral way, but it can sometimes muddy the clarity of sentence structure, especially in more formal contexts. The use of "his" or "her" alone also does not capture the inclusivity of both male and female members of the team, further emphasizing that "his or her" is the most precise choice in this instance. This adherence to traditional grammar rules allows for clearer communication, particularly when discussing the positions or statements of individuals within a group.
