Answer 1

The correct answer is Opposite decussate.

Key Points

Phyllotaxy is the arrangement of leaves on a plant stem. In the case of Calotropis (a genus of flowering plants in the dogbane family), the phyllotaxy is opposite decussate.
In an opposite decussate arrangement, pairs of leaves are arranged at right angles to the pair above or below them on the stem.
This type of leaf arrangement is fairly common in many plant species.

Additional Information

Alternate phyllotaxy is where there is only one leaf per node and they alternate sides as you move along the stem.
Opposite superposed is where two leaves arise at the same level but directly above the pair of leaves in the next node below.
Ternate phyllotaxy is where three leaves are arranged at each node.
