C Correct answer
Explanation

Huntington's chorea, Phenylketonuria (PKU), and Tay-Sachs disease are all genetic disorders caused by inherited mutations in specific genes. Rheumatic heart disease, however, is an acquired condition resulting from rheumatic fever - itself a complication of untreated or poorly treated streptococcal throat infection caused by Group A Streptococcus bacteria. It is not inherited genetically but develops after infection.
