Which of the following is NOT mentioned as a means by which an orchid attracts insects?

A. Size.
B. Shape.
Color.
D. Scent.

To lure their pollinators from afar, orchids use appropriately intriguing shapes, colors, and scents. At least 50 different aromatic compounds have been analyzed in the orchid family, each blended to attract one, or at most a few, species of insects or birds. Some orchids even change their scents to interest different insects at different times.
Once the right insect has been attracted, some orchids present all sorts of one-way obstacle courses to make sure it does not leave until pollen has been accurately placed or removed. By such ingenious adaptations to specific pollinators, orchids have avoided the hazards of rampant crossbreeding in the wild, assuring the survival of species as discrete identities. At the same time they have made themselves irresistible to collectors.
The orchid is unique because of______.

A. the habitat in which it lives
B. the structure of its blossom
C. the variety of products that can be made from it
D. the length of its life
