Which statement about racemose inflorescence is true?

Explanation:
Racemose inflorescences are indeterminate, meaning the main axis keeps growing and can bear new flowers along its length. The growing tip isn’t halted by a flower, so growth is unlimited. This is why the statement about unlimited growth is the true description: the inflorescence keeps elongating and producing flowers down the axis, with older flowers typically toward the base and younger ones toward the tip. The other notes don’t define racemose growth. If the peduncle ends in a flower, that describes a determinate (cymose) pattern, not racemose. A bract can be present in many inflorescences and doesn’t distinguish racemose growth. Flowering order along the axis can vary and isn’t a universal feature of racemose types, so basipetal arrangement isn’t a reliable universal trait for identifying racemose inflorescences.
