The most logical organizational structure for the article "Fresh from the Field to Your Table", by Chris Boyle, would be d) compare/contrast.
In this article, we are presented with the picturesque scenes of this Farmers Market on Famingdale's Main Street and we are introduced to the products that the vendors sale there.
After this introduction, the article focuses on the comparison/contrast of different testimonies and the experiences of different vendors, and how they would describe the impact of the Farmers Market in the community.
