c. White cheeked macaque

d. None of the above

ANSWER: Grauer’s gorilla

Explanation:

Grauer’s gorilla, the world’s largest primate has worried conservationists given their dwindling number

DRC left experts worried after the gorilla population plummeted 77% over past 20 yeas with less than 3800 of animals remaining

Grauer gorrila is named after Rudolf Grauer, an Austrian explorer who first recognized the apes as a separate subspecies

They resemble the mountain gorilla, save for their longer limbs and shorter hair. The gorillas survive on bushmeat and can weigh up to 400 pounds.

In 1994, the Wildlife Conservation Society conducted surveys in and around eastern Zaire and had estimated that 17,000 Grauer's gorillas remained.

But the Rwandan genocide that year led to the gorillas' precipitous decline.
