Answer:
Correct Answer: D
Solution:
In spiral arrangement, each node bears a leaf and the leaves of the adjacent nodes roughly lie towards the opposite sides.
In opposite arrangement, two leaves are borne on the opposite sides of a single node.
When three or more leaves develop on the nodes, they form whorled arrangement.
