In an inflorescence where flowers are borne laterally in acropetal succession, the position of the youngest floral bud shall be

1. proximal

2. distal

3. intercalary

4. anywhere


In racemose inflorescence younger flowers are born at the apex or distal end while older flowers are at the base, this type of succession is acropetal succession. Thus, the position of youngest floral but would be distal.
