Answer:
B) Wild animals have less total fat than livestock fed on grain and more of a kind of fat thought to be.
Step-by-step explanation:
The above statement best exemplifies the comparison stated in the paragraph. The first option has 'they think of' which makes it inappropriate comparison. The third uses 'that of' which here seems illogical. The fourth and fifth option suggest a wrong comparison as both are irrelevantly structured. Thus, we are left with B that suggests the correct comparison and conveys it more effectively.
