The correct answer is c. unions. In certain industries, unions play a crucial role in determining wages and working conditions. Unions are organizations formed by workers to negotiate with employers on behalf of the employees. They advocate for better wages, benefits, hours, and overall working conditions. When it comes to industries like automobiles and agriculture, unions have a strong presence and bargaining power. They negotiate collective bargaining agreements with businesses, which establish the terms and conditions of employment including wages. Businesses are then obligated to comply with these agreements and pay the wages specified by the unions.
