Related Formula
Racemose: Continuous main axis growth, Acropetal floral arrangement. Cymose: Limited main axis growth (terminates in flower), Basipetal floral arrangement.
Core Logic
In racemose inflorescence, the main shoot axis continues to grow indefinitely and produces flowers laterally in an acropetal succession (older flowers at base, younger towards apex).
Step 1: Selection
Flowers are borne in an acropetal succession. Option (3) is correct.
Pattern Recognition
Racemose = Acropetal succession & indefinite axis growth.
