Correct option (b) pseudocopulation
Explanation:
For its pollination, the orchid ophyrys speculum has picked on the most selective attraction in the entire animal kingdom. It ls pollinated by a hairy wasp, Colpa aurea. The wasp has a fixed habit whereby lts males leave the burrows for above ground existence about four weeks before the females emerge for the open-arr mating.
The orcind opens its flowers about the same time the males appear and they possess an appearance and odour similar to those possessed by the famele wasps. The inexperienced males mistake the Ophrys flowers for their female counterparts and land to perform the act of pseudocopulation. The insect repeats the act with a number of orchid flowers and carries pollinia from one flower to another. This insect-plant relationship is beneficial only to the plant.
