Which one of the following most accurately states the main point of the passage?

I have a question about this one. I picked answer choice "C" for this one which is correct. My question to you though is, is the line, "As a possible solution, agricultural researchers, development experts, and policy makers are searching for ways to conserve the wealth of genetic information contained in crops known as heirloom varieties." a direct paraphrase of what the main point of the passage is about? It seemed to me that it is.
