Its either B or D...... B if the whole story is about him trying for the team and D if that is a big part of the story. Hope I Helped!
Each word is first shown as it is commonly misspelled. Is the answer to the question.
I would go with B, or Ways to build immunity to diseases. Why? Well, just by using the word biology, we can use process of elimination. The prefix “bio” means life, so C and D already would be out. The suffix “ology” means the study of, so the word biology means the study of life. Because biology often has to do with diseases and finding cures to sustain human life spans, the only logical answer would be B. A would make no sense in terms of biology.
