The logic followed is: All the given options except option (3), is native to the Artic whereas camel lives in hot and dry climate i.e deserts. Option 1: Polar bear The polar bear is a hypercarnivorous bear whose native range lies largely within the Arctic Circle, encompassing the Arctic Ocean, its surrounding seas and surrounding land masses. It is the largest extant bear species, as well as the largest extant land carnivore. Option 2: Arctic wolf Often called the "polar wolf" or "white wolf," Arctic wolves inhabit the Arctic regions of North America and Greenland. Option 3: Camel Camels live in deserts, where it is hot and dry. Camels have adapted and found ways to help them survive in deserts. Option 4: Musk ox The Musk ox, also spelled musk ox and musk-ox, is a hoofed mammal of the family Bovidae. Native to the Arctic, it is noted for its thick coat and for the strong odor emitted by males during the seasonal rut, from which its name derives. Thus option 3 is different from rest of them. Hence, the correct answer is "Camel".
