The complete sentence in each group is:

1. Kelley studies the effects of the chemicals in chocolate.

To identify the complete sentence in each group, we need to look for a group of words that forms a grammatically correct statement and expresses a complete thought.

In group A, there are four phrases provided:

1. Anne E. Kelley, a professor at the University of Wisconsin.
2. Kelley studies the effects of the chemicals in chocolate.
3. Including something called phenylethylamine.
4. May actually prevent several serious diseases.

To determine which of these are complete sentences, we need to consider if they have a subject and a verb, as well as express a complete thought.

Identifying the complete sentence:

1. Anne E. Kelley, a professor at the University of Wisconsin. - This is not a complete sentence. It is a noun phrase.
2. Kelley studies the effects of the chemicals in chocolate. - This is a complete sentence as it has a subject "Kelley" and a verb "studies," and it expresses a complete thought.
3. Including something called phenylethylamine. - This is not a complete sentence as it lacks a subject and a main verb. It is a participial phrase.
4. May actually prevent several serious diseases. - This is a complete sentence as it has a subject "May" and a main verb "prevent," and it expresses a complete thought.

Therefore, the complete sentence in group A is: "Kelley studies the effects of the chemicals in chocolate."
