Answer: (A)

Verified step by step guidance

1. Understand the key differences between eudicots and monocots, which are two major groups of flowering plants. Eudicots and monocots differ in several structural and developmental characteristics.
2. Recall that cotyledons are the seed leaves present in the embryo of a plant. Eudicots typically have two cotyledons, while monocots have only one cotyledon.
3. Examine the arrangement of vascular bundles in the stem. Eudicots have vascular bundles arranged in a ring, whereas monocots have scattered vascular bundles.
4. Consider the flower parts. Eudicots usually have flower parts in multiples of four or five, while monocots have flower parts in multiples of three.
5. Analyze leaf venation patterns. Eudicots typically have a net-like or reticulate venation pattern, while monocots usually have parallel venation.
