Question

selective breeding of wild mustard
wild mustard
kale
broccoli
cabbage
cauliflower
what can one infer about the relationship of these plants from the diagram given?
a selective breeding of cauliflower was used to cultivate traits to develop the other plants.
b broccoli, cauliflower, cabbage, and the mustard plants are all derived from kale through the process of natural selection.
c broccoli cauliflower, cabbage, and kale are similar in their appearances and taste because they have been derived from many different plants through the process of natural selection.
d broccoli, cauliflower, cabbage, and kale each have their own distinct appearances, but they have all been derived from the same plant (wild mustard) through the process of selective breeding.

Explanation:

The diagram shows that wild mustard is the common origin. Selective breeding (not natural selection as in B and C) was used. A is wrong as cauliflower isn't the base. D correctly states they are derived from wild mustard via selective breeding with distinct traits.

Answer:

D. Broccoli, cauliflower, cabbage, and kale each have their own distinct appearances, but they have all been derived from the same plant (wild mustard) through the process of selective breeding.
