c i think but im not entirely sure to be honest with you
Scientists believe that great apes such as chimpanzees and gorillas are more closely related to humans based on the evolutionary timeline because apes are larger than monkeys and have long legs and no tails. Apes are known to have larger brains than monkeys which makes them so closely related to us. This fact cancels out B and C for the answer. Also, apes (gorillas, orangutans, etc.) are much larger than monkeys (mandrill, lesula, etc.). This right away cancels out option D. What's left is option A which features body parts and comparisons that are comparatively accurate towards humans. Hope this helped :))
I'm assuming there is a graph to go along with the question but as a guess, The numbers of lynx and rabbits flow as opposites when rabbit population goes up soon after the lynx population wil also go up due to increase in food, then the rabbit population will go down due to the increase in predators. This patern will continue on.
They may have evolved from a common ancestor.
