The answer is d: All of the above.

Explanation for each option:

a. They are highly social and intelligent and therefore easy to train.

• This is correct. Rats are known for their intelligence and social nature, which makes them relatively easy to train for specific tasks, including detecting landmines.

b. They are extremely sensitive to smell and have more genetic material dedicated to olfaction than any other mammal.

• This is correct. Rats have a highly developed sense of smell, which is crucial for detecting the chemical compounds associated with landmines.

c. They can be trained to communicate with a human trainer when it smells a target.

• This is correct. Rats can be trained to signal to their human handlers when they detect the scent of explosives, making them effective in landmine detection.

Since all the options are correct, the best choice is d: All of the above.
