The correct answer is C) both a and b.
Some labor unions embraced socialism because they wanted to protect the workers’ rights and they wanted governmental control over most businesses.
After many years of labor oppression in the workplace, workers started to form labor unions to demand justices and fight for their rights. Many workers that labored in factories and manufacturing plants worked under harsh and unhealthy conditions. They even worked for long periods. That is why they gathered together and formed unions that demanded the government's support and intervention to regulate business such as the oil and steel industries.
