The correct answer is forming.
In terms of Tuckman's theory of group development, the first stage of group development is called forming. This stage involves members of a group coming together for the first time. Group members typically learn about one another, see if they can form common ground,understand what their goals and mission as a group and decide how to proceed further with delegation duties and roles. In this initial stage of group formation, members are typically ambivalent and non-committal.
