Which example indicates obsessive-compulsive disorder?

Washing or cleaning Washing hands excessively, sometimes until they are raw and bleeding. There are many other types of washing behaviors, including:

Checking These types of compulsions can involve checking doors, locks, or backpacks, to make sure everything is safe. Some children and teens check to make sure that everyone is okay. For example, calling family members to "check" that they are safe.

Counting, tapping, touching, or rubbing Compulsions can involve counting, touching, or tapping objects in a particular way. Some children and teens have lucky and unlucky numbers involved in their rituals (e.g., needing to touch a door four times before leaving a room).

Ordering/arranging This compulsion involves arranging items in specific ways, such as bed sheets, stuffed animals, or books in the school locker or book bag. For example, a child might need to line up all the shoes in the closet so that they all face forward, and are matched by color.

Mental rituals Not all children and teens with OCD will have compulsions that can be seen. Some perform rituals in their head, such as saying prayers or trying to replace a "bad" image or thought with a "good" image or thought. For example, a teen might have a bedtime prayer that he or she mentally repeats over and over again until it "feels right".
