The correct answer to the question is B: Give the giraffe a carrot.
Here's why:
1. Giraffes are herbivores, meaning they primarily eat plants. Offering a giraffe a carrot would be a suitable and enjoyable treat for it.
2. Carrots are a healthy snack for giraffes as they are rich in vitamins and minerals that can contribute to their overall well-being.
3. Giving a giraffe a carrot as a treat can also be a positive way for the zookeeper to interact with the animal, promoting a sense of care and connection.
4. Moving the giraffe to a different zoo (option A) is not necessary for offering a treat. Pulling on the giraffe's horns (option C) is inappropriate and could harm the giraffe. Going for a walk with the giraffe (option D) might not be practical or safe in a zoo setting.
In conclusion, giving the giraffe a carrot is the most appropriate and safe choice for the zookeeper to offer a special treat to the giraffe.
