please select the best answer from the choices provided.

Explanation:

Hypertension earns the "silent killer" label because most people have no noticeable symptoms for years, even as it damages blood vessels and organs silently until a major event like a stroke or heart attack occurs. Option A is incorrect as it does not kill during sleep specifically, B is wrong as there are treatments for hypertension, and D is false as it does not target the voice box first.

Answer:

C. it generally has no symptoms
