Chasmogamy is a plant with a reproductive mechanism in which pollination occurs in chasmogamous flowers. Chasmogamous flowers are showy with open petals and encircling exposed reproductive parts.  Chasmogamous stems from Greek for an open marriage. These are named after the open arrangement of floral structures. 

Once chasmogamous flowers have reached maturity, they unfurl and their stamens and/or style are made available for pollinations correct answer is Chasmogamy, is pollination in open flower.

Thus the correct answer is C.

Mixed pollination, involving the application of compatible pollen alongside incompatible pollen, can sometimes overcome self-incompatibility barriers in plants.

Bombax ceiba (the silk cotton tree) is well-known for being pollinated by bats, a process known as chiropterophily.

Anemophilous flowers have certain characters like:-

Oaks are deciduous trees belonging to the genus Quercus that produce inconspicuous flowers lacking petals. They rely on the wind to carry vast amounts of lightweight pollen from male to female catkins, making wind pollination (anemophily) their primary mechanism.

The pollen grains which are very light in weight can be passed on by wind from one flower to another or to the stigma of the same flower. This is known as wind pollination. They produce light weight pollens in large number and do not produce vector. The stigma is sticky.

Yucca is the pollinated by a moth known as the Tegeticulla yuccasella.  Each spring, adult moths emerge from the underground cocoons. And the males and females meet up with each other on Yucca plants for mating.

The Yucca moth is also termed as the pronuba moth. It is a small white moth that lives in the semi-arid habitats where Yucca plants grow.

Thus the correct answer is A.
