Dadaists were artists who tried to express in their art their revulsion for what they saw as the insanity of life. The correct option among all the options given in the question is the second option. Dadaism is actually a post World War I cultural movement in literature and visual art. It was actually a protest made against the barbarism of war as a whole. 

Dadaists were artists who tried to separate everyday objects from their normal contexts. This can be seen in their works which were often quite different compared to the usual works of artists at the time.
