Many animals have died out. Which of these is extinct?

The quagga is an extinct subspecies of plains zebra that lived in South Africa until the late 19th century. It was unique among zebras because it had zebra stripes only on the front part of its body, while the rear was brown. The last quagga died in captivity in 1883. All other options (raccoon, hippo, anteater) are extant species that still exist today. The quagga is a classic example of human-caused extinction.
