The correct answer is D. Miller.

The first cytokinin was discovered by F. Skoog and C. Miller in 1955. They isolated the compound from DNA and found that it promotes cell division, a key role of cytokinins in plant growth.

Here is a breakdown:

A. Skoog: Known for his work in plant growth hormones and tissue culture.
B. Went: Known for his work on auxins, another type of plant hormone.
C. Addicott: Contributed to plant hormone research, particularly on abscisic acid.
D. Miller: F. Miller, along with Skoog, discovered the cytokinin.
Therefore, the correct answer is D. Miller.
