The original 1997 recording lineup of Destiny’s Child had four members.
That lineup consisted of Beyoncé Knowles, Kelly Rowland, LaTavia Roberson, and LeToya Luckett. The four-member group recorded “No, No, No,” which became Destiny’s Child’s breakthrough single and appeared in two parts on the group’s early release.
The lineup later changed substantially. Farrah Franklin and Michelle Williams joined in 2000, but Franklin left after a short period. Roberson and Luckett departed after the group’s first major era, leading to the trio of Beyoncé, Kelly Rowland, and Michelle Williams that became most associated with Destiny’s Child.
This question concerns the 1997 recording lineup, not every person who was ever a member. The group’s earlier pre-Destiny’s Child name, Girl’s Tyme, also had changing membership. Those shifts can make sources appear inconsistent unless the year and lineup are specified.
