• B. Multiparous chyme
• C. Capitulum

Answer 1

The correct option is D Scorpiod cyme

In the cymose inflorescence the main axis ends of the flower ends in a flower as the peduncle stops growing. The flowers in cyme show basipetal succession. The oldest flower is the apex and the youngest flower of the inflorescence is at the base of the inflorescence. The flower are arranged in centrifugal manner and the oldest flower is at the center and the young flowers are towards the margin. A cyme is said to be scorpioid when the axis is curved and the flowers arise two-ranked and on alternate sides of the axis as in the forget-me-not. Rhipidium is a fan-shaped cymose inflorescence (as in some sedges) in which the branches lie in the same plane and are suppressed alternately on each side.
Therefore, the correct option is D.
