C. Different species can share the same common name.
<h3><u>Explanation;</u></h3>
- <em><u>Different organisms can share the same common name</u></em>, and thus the reason why scientists avoid using common naming while naming organisms.
- Additionally, s<em><u>cientists avoid using common names because they are not specific to a specific species.</u></em> For instance, Robin is a common word that may be used to describe the many species of robin that are found in different regions of the earth, for example, Robin in England which has yellow breast, and robin in United states and have red breasts.
- Therefore, <em><u>for the purpose of avoiding ambiguity and confusion in naming organisms scientists use scientific names while identifying various species.</u></em>
