_____ is a type of spontaneous group discussion to help find multiple solutions for problems.

A) Brainstorming
B) Groupthink
C) System justification
D) Force field analysis

Brainstorming is a technique used to encourage creative thinking and generate multiple solutions or ideas to a problem. It involves a group of individuals sharing their ideas in a spontaneous and non-judgmental manner, with the goal of generating as many ideas as possible. Groupthink is a different phenomenon, in which group members prioritize harmony and consensus over critical evaluation of ideas. System justification and force field analysis are also different concepts not related to spontaneous group discussion for finding multiple solutions to problems.
