Solution
The correct option is B Exocrine glands
Chemical communication plays a very important role in the lives of many social insects like ants and termites. Different types of pheromones (species-specific chemical messengers) have been described, particularly those involved in recruitment, recognition, territorial and alarm behaviours. Properties of pheromones include activity in minute quantities (thus, requiring sensitive methods for chemical analysis) and specificity (which can have chemotaxonomic uses). The sources of the pheromones are exocrine glands located all over the insect's body. The principal exocrine structures considered pheromone-producing glands are the Dufour, poison, pygidial, frontal, mandibular, salivary or labial, sternal, and tergal glands.
