Peasants made up percent of the third estate. a. 0 b. 10 to 15 c. 75 to 80 d. 100

I believe the answer is C. 75 to 80
Peasants make up the majority of the third estates and lived in a very poor condition. Despite their harsh situation, the nobles and the churches at that time still requires them to give half of their income as tax payments which resulted in built up resentment towards the upper society.
