Explanation:
The survivorship curves refer to the graphical representation of the proportion of the fraction of survivors or the individuals at a given age.
There are three types of survivorship curves which can be constructed by studying the life history of the organisms.
The type I survivorship curve is the curve which can be formed with the organism which has a high survival rate at the younger and middle age and high death rate at the older age. The type I curve can be characterised by its convex shaped. The type I is showed by the large mammals like gorilla, humans and many others.
Thus, large mammals such as gorillas are the correct answer.
Because since their ancestors came before them then they inherit certain beneficial traits that help them survive. Those traits are in the DNA and the animals are evolving to be more fit for the environment that they are in. (hope this helps)
