Vedclass · Answer

(C) Segmentation,also known as metamerism,is a characteristic feature where the body is externally and internally divided into segments with a serial repetition of at least some organs.Among the given options,$Arthropoda$ and $Chordata$ both exhibit true segmentation.$Arthropoda$ shows metameric segmentation,and $Chordata$ (specifically in vertebrates) shows segmentation in the form of vertebrae and muscles.Since the question asks for a phylum where segmentation is shown,and both $Chordata$ and $Arthropoda$ exhibit this trait,the most appropriate answer is that both are correct. However,in standard multiple-choice contexts,if $Arthropoda$ is the primary focus of the subtopic,it is a classic example. Given the options provided,$Chordata$ and $Arthropoda$ are both segmented.
