Why (B) is correct: There are two major types of inflorescences defined based on the fate of the apical meristem: Racemose and Cymose. In racemose inflorescences, the main axis continues to grow indefinitely, and flowers are borne laterally in an acropetal succession. In cymose inflorescences, the main axis terminates in a flower, thus limiting its growth, and flowers are borne in a basipetal succession.
Why other options are wrong:
- (A) 3: There are not three major types based on this specific criterion.
- (C) 4: There are not four major types based on this specific criterion.
- (D) 5: There are not five major types based on this specific criterion.
NEET Tip: Remember that the key difference lies in whether the main axis (apex) continues to grow (racemose) or terminates in a flower (cymose).
Correct Answer: (B)
