Which paragraph written to build interest presents a dual appeal?

a.Now you can be good to yourself and do good for the environment. How, you ask? Become a member of Fair & Fresh Farming and start ordering seasonal fruit and vegetables from the small local farm to your table. Best of all: pay only a little more than conventional supermarket food prices.

b.Revel in knowing that while nourishing your body, you are also aiding our Mother Earth. Taste the crunch of farm-fresh fruit and vegetables and say goodbye to bland supermarket produce forever!

c.It goes without saying that shorter travel also means saving time and resources. Why burn gasoline by going to the supermarket where you will jostle with a crowd in the aisles, when your produce is just a click away?
