Answer:
Option D
Explanation:
Please see the images for this question attached here.
Solution
The evolving branch is the one which keeps on growing and diversifying. In the first image attached herewith, the branches with send species as trout and mouse are not evolving. Hence both options A and B in the first image are incorrect.
In the second image, all the branches are shown as evolving which is also not true and hence option C is correct.
However, the last image in which only the upward branches are marked red is the correct images. All the upwards branches are evolving all together with any diversification at the end species.
Hence, option D is correct
