Explanation:

1. Immunodeficiency diseases are conditions where the immune - system is compromised. AIDS is a well - known immunodeficiency disease. Ear infections are common infections not specifically immunodeficiency diseases. Malformed extremities are related to developmental issues, and heart disorders are related to the heart, not directly to immune deficiency. So for the first question, AIDS is the correct choice.
2. AIDS is caused by the human immunodeficiency virus (HIV). Kaposi sarcoma is a type of cancer that can occur in people with AIDS due to their weakened immune system. Multiple myeloma is a cancer of plasma cells, and systemic lupus erythematosus is an autoimmune disease.

Answer:

Question 1: B. AIDS
Question 2: B. human immunodeficiency virus
