A disadvantage of using common names for identifying organisms is that they

• A. Provide little information about the relationship of one organism to another
• B. Are universal across languages
• C. Can be easily used in scientific discussions
• D. Are standardized for all regions

Answer: (A)

Common names create ambiguity because they don’t reveal how organisms are related and they vary by language and region. A single common name can refer to different species in different places, and different names can refer to the same species. That means you can’t reliably judge relatedness, characteristics, or proper management just from the name. In agricultural practice, this ambiguity can lead to misidentification and inappropriate control or treatment decisions. Scientific names solve this by using a standardized, worldwide system (genus and species), which clearly communicates which organism is being discussed and its relationships to others. The other statements aren’t accurate: common names are not universal across languages, they aren’t standardized for all regions, and they aren’t easily used in precise scientific discussions due to their variability.
