Correct Answer:

- Option A (Dr. Ruth Pfau) is correct. Dr. Ruth Pfau was a German-Pakistani nun and physician who devoted over 50 years to fighting leprosy in Pakistan. Her tireless efforts and profound impact on public health earned her this revered title.
- Option B (Benazir Bhutto) was a prominent Pakistani politician and former Prime Minister, known for her political career, not for the specific humanitarian work associated with the title.
- Options C (both) and D (none) are incorrect because Dr. Ruth Pfau is the specific individual recognized by this honorific.
