Which of the following shows a whorled phyllotaxy?

📌Concept:
-The arrangement of leaves on the stem or the branch of a plant is called phyllotaxy.
-There are three different kinds of phyllotaxy: alternate, opposite, and whorled.

✅Explanation:
-Alternate
-In this case, a single leaf arises at each node.
-The leaves are arranged in an alternate manner.
-It is observed in china rose, mustard, and sunflower.
-Opposite
-In this case, a pair of leaves are arranged on either side of the node.
-The leaves lie opposite each other.
-It is observed in Calotropis. 
-Whorled
-​If more than one leaf arises from a node and forms a whorl, the kind of phyllotaxy is called whorled phyllotaxy,
-It is observed in Alstonia.
In a line transect of length L and half-width w, designed for estimating the density of gaur (∼ D=N/2Lw), N animals were counted.
