My answer will be option C. "The manufacture of tools was a defining characteristic of humans." This is because scientists have been evidencing and documenting for some time how these primates create basic tools for their subsistence. An example of this was in the year 2010, where Kendal, R. L., et al. published in a study called "Evidence for social learning in wild lemurs (Lemur catta)" a paper explaining that ring-tailed lemurs had been able to manipulate an artificial feeder to access the food it contained, which is the first case documented use of tools by these primates in freedom.
