Correct answer: D. Adenosine deaminase
- A. Hypoxanthine-guanine transferase
- B. Xanthine oxidase

- D. Adenosine deaminase
Explanation
The deficiency of Adenosine deaminase (ADA) causes immunodeficiency. ADA is an enzyme that is responsible for breaking down adenosine, a type of nucleic acid. When ADA is deficient, adenosine builds up in the body, which can damage the immune system. This can lead to a variety of immunodeficiency disorders, including severe combined immunodeficiency (SCID).
