based on the scatter diagram below, answer the questions below

permeability index Y b. Is there a relationship between permeability and carbon content? A. No, there does not appear to be a relationship between permeability and carbon content. B. Yes, there is a relationship between permeability and carbon content, although it is does not seem to be very str C. Yes, there is a very strong relationship between permeability and carbon content. c. If low permeability is desirable, what does the scatter diagram suggest with regard to the carbon content? A. Carbon content must be increased to reduce the permeability index. B. Changing the carbon content does not affect the permeability index. C. Carbon content must be decreased to reduce the permeability index
