The correct option is C 102,42
The inflorescence in the Bougainvillea
flower is a simple cyme or cymule. In the cymule, the peduncle ends in a flower
and only 2 lateral branches. These are produced which also ends in flowers.
Thus, 3 flowered inflorescences will be formed. Flowers are arranged in a
basipetal manner. Since the inflorescence number will be given here 34. Thus,
the total numbers of flowers would be 34×3=102.
Single female flower-like inflorescence of
the Euphorbiaceae i.e. Poinsettia is called a cyathium. The single female
flower of cyathium has 3 carpels syncarpous pistil. Also, the inflorescence
number given here is 42. Thus hence the number of female flowers is 42.
So, the correct answer will be 102,42.
