Answer

(d) Ornithophilous – Butea/Palash/Flame of the Forest

Explanation

Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of a different flower. The mode of pollination depends on the agent that carries the pollen. Ornithophilous plants are pollinated by birds. The Butea or Palash, also called Flame of the Forest, is pollinated by birds, hence classified as ornithophilous. Other modes are: anemophilous (wind), hydrophilous (water), and entomophilous (insects), but their plant examples differ from the options provided.
