Who developed minimal group paradigm?

The correct answer is Option (1) → Tajfel and colleagues

Tajfel and his colleagues wanted to know the minimal conditions for intergroup behaviour, and developed the minimal group paradigm to find out. British schoolboys were divided into a ‘Kandinsky group’ and a ‘Klee group’ only by their preference for paintings, and were asked to distribute money among others known only by code number and group. Even in such flimsy groups, with no past and no future, the children favoured their own group.
