Correct Answer: Option A
Explanation:
Phyllotaxy is the pattern of leaf arrangement on the stem. In sunflower (and many other plants like mustard), the phyllotaxy is alternate, meaning a single leaf arises at each node. In opposite phyllotaxy (e.g., guava), two leaves arise at a node, and in whorled (e.g., Nerium), more than two leaves arise at a node.
