This question is unfortunately incomplete. This question relates to the advantage derived by some parasites by maintaining a low level of infection in the host. These parasites achieve this by a gene for its surface glycoproteins that is duplicated thousands of times, with each gene coding for a slightly different glycoprotein structure. By constantly shifting between glycoproteins of different structures, the parasite can fool the host into temporarily reversing the immune response. The question includes a table showing the change in parasite blood concentration with time, with the table showing distinct waves of increases in parasite concentration followed by decreases. Using the hypothesis about changing glycoprotein structure, it makes sense that the host begins an immune response, leading to a decrease in parasite numbers, at which point the parasite changes the structure of its surface glycoproteins, thereby allowing the parasite to overcome the immune response, and the concentrations of parasites increase once again.

Answer:
The correct answer is a. Reduction in species diversity
Explanation:
In habitat fragmentation, the large area of forest is divided into many smaller patches which reduce the area of habitat for species live there. This Fragmentation of habitat occurs mainly due to human activities like making highways and roads in the area.
This separates species member from each other which reduces the gene flow between that which can lead to inbreeding depression in a species and extinction of species can occur.
Cutting trees and human activities can alter the environment negatively which can cause extinction of some species that reduce species diversity. So the correct answer is a.
