I believe that both are complete sentences.
"D. My mother or my father is going to pick me up from swim practice" is the only sentence that contains an error in subject-verb agreement, but this is common.
Learning about confirmation biases has allowed me to avoid this common logical flaw in my thinking when conducting research. It prevents me from looking for information that only supports my hypothesis when conducting a literature review or deriving conslusions from my paper. In the early stages of research, for example, I do not only look for information that can support my preexisting beliefs or hypothesis, but rather I search for articles that provides a more enriching an objective information about the subject matter. In addition, In the late stage f a research paper, conclusions are derived based on objective evidence and not on preexisting beliefs.
