The correct answer is A) al-Razi.

Explanation:

1. Al-Razi (Rhazes): He is often recognized as one of the pioneers in the field of medicine and is credited with identifying the contagious nature of diseases. He conducted significant studies on smallpox and measles, emphasizing the importance of observing patients and their symptoms to understand disease transmission.

2. Ibn Sina (Avicenna): While he made substantial contributions to medicine and is known for his work "The Canon of Medicine," his focus was more on the theoretical aspects of health than on the direct observation of disease spread.

3. Ibn Khaldun: Primarily known for his work in sociology and historiography, he did not specialize in medicine.

4. Al-Khawarizmi: He is best known for his contributions to mathematics and astronomy, not medicine.

Therefore, al-Razi stands out as the Persian doctor who notably contributed to understanding how diseases were spread from person to person.
