Sharks have a higher ratio of cartilage mass to body mass than any other organism. They also have a greater resistance to cancer than any other organism. Shark cartilage contains a substance that inhibits tumor growth by stopping the development of a new blood network. In the past 20 years, none of the responses among terminal cancer patients to various therapeutic measures has been more positive than the response among those who consumed shark cartilage.

Summary
The ratio of cartilage mass to body mass is the % of an animal’s mass that is made of up cartilage. This % is higher for sharks than it is for any other organism.
Sharks have a greater resistance to cancer than any other organism.
Shark cartilage has a substance that inhibits tumor growth.
In the past 20 years, the response of terminal cancer patients to eating shark cartilage has been therapeutically better or as good as any other response of those patients to other treatments.

Notable Valid Inferences
There’s no clear inference to draw. I’d rely on process of elimination to identify which answer must be false.

A
No organism resists cancer better than sharks do, but some resist cancer as well as sharks.
Must be false. We know sharks have a greater resistance to cancer than any other organism. So it’s impossible for some organisms to resist cancer as well as sharks.
B
The organism most susceptible to cancer has a higher percentage of cartilage than some organisms that are less susceptible to cancer.
Could be true. We know about how sharks’ cartilage ratio compares to other animals. But we don’t know about how one non-shark animal’s cartilage ratio compares to another non-shark animal.
C
The substance in shark cartilage that inhibits tumor growth is found in most organisms.
Could be true. Sharks have a substance that inhibits tumor growth, but most other animals could have this, too. Sharks may just have more of this substance than other animals.
D
In the past 20 years many terminal cancer patients have improved dramatically following many sorts of therapy.
Could be true. Many therapies can help patients. Eating shark cartilage works as well or better than those therapies, though.
E
Some organisms have immune systems more efficient than a shark’s immune system.
Could be true. The stimulus doesn’t tell us about the efficiency of a shark’s immune system. We know about resistance to cancer, but that doesn’t guarantee anything about overall immune system efficiency.
