III. Leaflets of the compound leaves

The leaves:
I. Develop at the node, bear buds in their axil that later develop into a branches.
II. Originate from shoot apical meristems and are arranged in an acropetal order.

Identify the correct statements amongst the following:
I. When a shoot tip transforms into a flower, it is always solitary
II. In racemose inflorescence, the main axis continues to grow and flowers are borne in basipetal order
III. In cymose inflorescence, the main axis terminates in a flower and flowers are borne in basipetal order

Consider the two statements:
Statement I: In racemose type of inflorescence, the main axis terminates in a flower, hence is limited in growth and the flowers are borne in a basipetal order.
Statement II: In cymose type of inflorescence, the main axis continues to grow and the flowers are borne laterally in an acropetal succession.
