Which of the following is not considered evidence supporting the evolutionary relationship among all plant taxa?

a. Plants share a significant number of genes

b. Plants and plant ancestors have chlorophyll

c. Fossils of plants show us transition series and evolutionary patterns of plants

d. Structures/characteristics among most plants are very similar

The correct answer is option d. "Structures/characteristics among most plants are very similar".

Explanation:

There are extensive evidence to support the evolutionary relationship among all plant taxa, however, similarity of structures and characteristics among most plants is not one of them. Plants are one of the most diverse kingdoms having very different species such as flowering plants, conifers, lichens, cycads, algae, among others. The structures and characteristics of these plants are very different among them, and this diversity makes difficult to classify and clarify the evolutionary relationship that they share.
