Correct option (d) malacophily
Explanation :
Pollination by snails and slugs is called malacophily. Snails perform pollination in Arisaema (snake or cobra plant) and some arum lilies. Entomophily is the most common type of zoophily in which the pollen grains of ripe anthers of one flower are transferred to a mature stigma of another flower through the agency of insects like moths, butterflies, wasps, bees, beetles etc. Ornithophily is the mode of allogamy (cross pollination) performed by birds. Chiropterophily is cross pollination performed by bats.
