The correct answer is:
b. to cover yourself in oil
Self-anointing is a behavior seen in some animals where they cover themselves in certain substances, often oils or secretions, to either mask their scent, protect their skin, or as a form of communication with other members of their species. An example of this behavior is observed in capuchin monkeys, where they rub themselves with millipedes to repel insects and potentially treat skin conditions. This behavior is not about covering oneself in spit, grading your own paper, or being dangerous. Instead, it serves a specific purpose related to the animal's survival or social interaction.
