The correct option is E Floral parts as multiples of four or five
Monocotyledons are vascular plants, which produce seeds, that develop from flowers and are enclosed in fruits. They have at least three of the following: flower parts are in 3's or multiples of 3; leaves are parallel-veined; vascular bundles are scattered throughout the cross section of the stem; seeds possess one seed leaf (cotyledon). Secondary growth from a vascular cambium is absent and pollen grains have one opening.
