The question was posed to me by my college director while I was bunking the class.

The origin of the question is Flowering Plants Morphology in section Morphology of Flowering Plants of Biology – Class 11

Answer 1

The correct choice is (c) Opposite phyllotaxy is present in China rose

To explain I would say: The arrangement of leaves in the plant is called phyllotaxy.  In alternate phyllotaxy, a single leaf is present at each node. This kind of phyllotaxy is seen in China rose. In whorled phyllotaxy, multiple leaves are present at each node.
