The correct answer is option C, that is, mammals were able to diversify to make use of the variety of habitats that were previously occupied by dinosaurs.
Adaptive radiation refers to the comparatively fast evolution of various species from a single common ancestor. Adaptive radiation usually takes place when a species enters a novel area and distinct traits influence its existence. An illustration of adaptive radiation is the progression of mammals after the annihilation of dinosaurs.  
 
        
             
        
        
        
Answer:
True breeding

<u>True breeding occurs in the plants when the plants produce offspring of same variety only when self pollination takes place.  </u>
<u>For example, if a plant has purple flowers will produce only seeds which will grow into plants which have purple flowers.</u>
