The correct option is C Annelida and Arthropoda
Metamerism is the phenomenon in which the body of organisms is constructed into a linear series of body segments. Organs and tissues in the body of such organisms are found to be repeated after regular intervals (segments) and each segment is known as a metamere or somite. This is seen mainly in annelids and is also found in arthropods. So, the correct answer is ' annelida and arthropoda'.
