Answer:
The correct answer is option E) "The presence of one or more introns".
Explanation:
Introns are non coding sequences located within genetic sequences that are removed during RNA maturation by a process known as RNA splicing. A gene that has 2000 nucleotide pairs but is translated into a mRNA molecule with 1200 nucleotides most likely have one or more introns that in conjunction are of 800 nucleotides in size. Once the intros are removed from the mRNA molecule the coding sequence is ready to be translated into a protein.

Planarias are flat worms that live freely in freshwater and sometimes in teh logs, soil, plants, or other dump or humid areas. They are from the class of Turbellarians. They have a very good ability in regeneration. They are acoelomerate which means that their body is very solid without any hollows.
They excrete unwanted objects from their body using their excretory system which is consists of series of tubes with length similar to their body length. The flame cells remove excess water through the use of the cilia and pass them to the ducts. At the end of the duct, there exist pores called the nephridiapores.
