The correct answer is A) improved agricultural productivity.
Beer Street and Gin Lane, William Hogarth, 1751. The migration to urban centers that is evident in the source is most likely a result of the following early modern process: improved agricultural productivity.
We are referring to the two cartoons made by William Hogarth in 1751, comparing the effects of drinking beer, instead of gin.
The migration to urban centers was a reaction of farmers that lived in rural areas that couldn't find work after new technologies improved agriculture with the invention of machines and new techniques. That is why people decided to move to the larger cities where the new industries and manufacturing plants were located and were offering jobs.
