{'primates': [0, 0, 2, 1], 'lemurs': [0, 0, 2, 1], 'kangaroos': [1, 0, 0, 0], 'animals': [0, 0, 1, 2], 'rabbits': [0, 0, 2, 1], 'giraffes': [1, 0, 2, 1], 'zebras': [0, 0, 2, 1], 'groups': [0, 0, 1, 0], 'koalas': [0, 0, 2, 1], 'hares': [0, 0, 2, 1], 'fol': [0, 0, 2, 0], 'lorises': [0, 0, 2, 1]}

The correct answer is option 3: Lemurs and Lorises. Primates are a group of mammals that include lemurs, lorises, monkeys, and apes. This group of animals is characterized by having forward-facing eyes, grasping hands and feet, and highly flexible limbs. Primates also have large brains relative to their body size and a complex social structure.

Option 1, which includes giraffes and zebras, is incorrect. Giraffes and zebras are not primates but are instead members of the ungulate group, which includes animals with hooves.

Option 2, which includes kangaroos and koalas, is also incorrect. Kangaroos and koalas are marsupials, not primates. Marsupials are a group of mammals that give birth to relatively undeveloped young, which complete their development in a pouch.

Option 4, which includes rabbits and hares, is also incorrect. Rabbits and hares belong to the lagomorph group, which is a separate group from primates.

Therefore, the correct answer is option 3: Lemurs and Lorises.
