I think it was Mike Durant.
The correct answer to this open question is the following.
Socialism and Communism were a response to the social and economic conditions that developed in Europe during the Industrial Revolution because the Industrial Revolution started a notorious economic inequity or disparity in the society. The wealthy owners of the industries became richer, meanwhile, the poor workers became poorer.
Two of the conditions that concerned socialist and communist thinkers were the low salaries that workers earned in the factories and the unhealthy conditions in which they worked. Workers labored for long hours daily under unhealthy conditions that created many risks, and of course, they did not have medical attention or insurance. The places had no ventilation at all and workers had to operate machines that created risks for the untrained workers.
Renaissance means "rebirth". After the fall of the Roman Empire in 476 AD, all of Europe was plunged into the Dark Ages, a time when education and intelligence was lost, and people sought solace in the idea that anything that they couldn't explain, like the solar system, was simply the work of God.
It was during the Renaissance that science and intellectual thinking finally started to make a comeback.
So, the answer is B.
