Which branch of medicine deals specifically with the care of children?

The correct answer is Pediatrics because this branch of medicine is dedicated to the health care and treatment of infants, children, and adolescents. Pediatricians specialize in various aspects of child development, preventive health care, and the diagnosis and treatment of childhood illnesses. Their training focuses on the unique physical, emotional, and social needs of young patients, ensuring they receive appropriate care at different stages of growth.

Other options pertain to different areas of medical specialization. Geriatrics focuses on the health care of elderly patients, often addressing age-related health issues. Oncology is the branch that deals with the diagnosis and treatment of cancer, affecting patients of all ages but primarily adults. Cardiology is concerned with heart-related health issues, primarily in adult populations as well. Understanding these distinctions highlights why Pediatrics is the appropriate answer for this question.
