Which sample offer the best summary

Sample A Genetically modified (GM) food exemplifies the tension between scientific uncertainty and consumer safety concerns. While peer-reviewed studies generally report no significant health risks, notable exceptions such as the "Monarch Butterfl controversy," "Pusztai case," and "Seralini case" have highlighted unexpected effect of GM crops. These controversies have damaged the public image of GM food, resulting in bans in 38 countries, including the EU. Risk evaluation is complex, with conflicting results raising concerns about potential carcinogenesis, teratogenesis, lethal effects, and fertility issues. Despite ongoing debates and some evidence of potential health effects from human and animal studies, the evidence remains inconclusive, and public concerns persist (Shen). Sample B According to Shen and others, the effects of genetically-modified food are inconclusive. Some studies showed no harmful effects but others did, resulting in more concerned public and some national bans. However, evidence for or against GM foods is still not certain
