The process of removing a young animal from its mother is referred to as "weaning." Weaning is the process of gradually reducing a young animal's dependence on its mother's milk or maternal care and transitioning it to a different diet or care routine. This process usually takes place over several weeks, during which the young animal learns to eat solid food and becomes more independent. Culling, breeding, and isolation do not describe the process of removing a young animal from its mother. Culling refers to the selective removal of animals from a group based on specific criteria, such as health or productivity. Breeding refers to the process of producing offspring through controlled mating. Isolation refers to separating an animal from others for various reasons, such as disease control. Therefore, the correct option is "weaning."
