Answer: C.) Cladistics is based purely on the shared characters between organisms and their ranking in evolutionary history.
  
Explanation:
Phylogeny is the evolutionary science which derives a relationship among the ancient species with their descendants based upon common genetic, physiological and morphological characteristics. Cladistics represent the study of a group of organisms which exhibit a common ancestor. A clade includes organisms having a common ancestors and exhibit similar traits in them. A clade is sufficient to include the organisms in a phylogenic tree based upon their evolutionary history. 
 
        
                    
             
        
        
        
Magnitude and direction
Explanation:
A vector quantity has both magnitude and direction. This is different from a scalar quantity that has only magnitude but no direction. 
- Examples of vectors are velocity, acceleration, displacement, momentum e.t.c 
- These quantities are physical quantities in which their magnitude has specific directions through which they are channeled.
