"Too often we try to solve human problem with non-human tools and in terms of non-human data. It is my simple thesis that a human problem requires a human solution. First we have to learn to recognise a human problem when we see one; and second, upon recognising it, we have to learn to deal with it as such and not as it were something else. A human problem to be brought to a human solution requires human data and human tools". Who said this?

Answer: Option D

FJ Roethlisberger, a prominent figure in the field of human relations and management, emphasized the importance of addressing human problems with human-centric approaches. His statement underlines the necessity of recognizing and addressing issues involving people with appropriate tools and data that consider the human element. Roethlisberger argued that human problems require human solutions, meaning that effective management and resolution of such problems necessitate understanding and empathy, rather than relying solely on impersonal data or mechanical tools.
