Solution

The correct option is B Attract each other
When a p-type impurity is added to a pure semiconductor, a hole is created due to lack of electron for chemical bonding. A free electron has a tendency to enter these holes, which means there is an attractive force between electron and hole. Thus holes behave like positively charged particles. Electrons being negatively charged, holes and electrons tend to attract each other.
