Which of the following groups has Se-jeong never been a part of?
Gugudan
I.O.I
Twice
Jellyfish Entertainment
Answer
Se-jeong has never been a part of Twice because she was not a member of the group when it was formed in 2015. She was instead a member of the girl group I.O.I, which was formed through the survival show Produce 101. I.O.I disbanded in 2016, and Se-jeong has since pursued a solo career.
