Concept:Nuptial flight in termites is the swarming flight of winged reproductive individuals to mate and establish a new colony.Explanation:Winged male and female termites leave their parent colony together in large numbers during nuptial flight.They mate during this flight, then come down to the ground and shed their wings.The paired termites then act as the king and queen and start a brand-new colony.This behaviour is not meant to escape bad weather, find food, or send signals to each other.Its main purpose is clearly to form new colonies.Answer:C. form new colonies
