The correct option is: (b) inflorescence
Explanation:
Composite fruits are multiple fruits which are developed from the complete inflorescence and are also called as infructescence. They are of two types-sorosis and syconus. Spike, spadix and catkin type of inflorescence gives rise to sorosis type of fruit e.g., Ananas, Artocarpus. Syconus develops from a hypanthodium inflorescence e.g. Ficus.
