Which of the following best explains the continuity in the trade routes between East Africa?

"If it were asked, why do we accept the theory of contagion, when already the divine law has refuted the notion of contagion, we will answer: The existence of contagion has been proved by experience, deduction, the senses, observation, and by unanimous reports. And it is not a secret to whoever has looked into this matter or has come to be aware of it that those who come into contact with plague patients mostly die, while those who do not come into contact survive. And amidst the horrible afflictions that the plague has imposed upon the people, God has afflicted the people with some learned religious scholars who issue fatwas* against fleeing the plague, so that the quills with which the scholars wrote these fatwas were like swords upon which the Muslims died. In conclusion, to ignore the proofs of plague contagion is an indecency and an affront to God and holds cheap the lives of Muslims."

Lisan al-Din Ibn al-Khatib, A Very Useful Inquiry into the Horrible Sickness, Granada, Spain, 1349-1352

The passage by al-Khatib is best understood in the context of which of the following?

"After leaving India, we arrived in Sumatra. It is a fertile area, in which coco-palm, clove, Indian aloe, mango, and sweet orange trees grow. Local commerce is facilitated by tin and Chinese gold. The sultan was informed of our visit and sent the judge and experts on Islamic law to meet me. The sultan is an illustrious and generous ruler and a patron of religious scholars. He is constantly waging war against the non-Muslims of Sumatra, but is a humble man who walks on foot to Friday prayers. The non-Muslims of the area must pay a poll-tax to obtain peace.
One Friday after leaving the mosque, the sultan mounted an elephant and we and his entourage rode with him on horses until we reached the palace. Male musicians came into the audience hall and sang before him, after which they led horses into the hall. The horses were embroidered in silk and wore golden anklets and danced before the sultan. I was astonished, even though I had seen the same performance at the court of the Delhi sultan in India*. My stay at the sultan's court lasted fifteen days, after which I asked his permission to continue my journey to China because it is not possible to sail to China at all times of the year.
We then traveled to a kingdom on the Malay Peninsula aboard a Chinese ship. This kingdom is inhabited by non-Muslims and contains great quantities of aromatic spices and aloes. The merchants sell Indian aloe for a roll of cotton cloth, which is dearer to them than silk. The ruler is a non-Muslim. We then left the Malay Peninsula and sailed to another non-Muslim kingdom in Southeast Asia. After seventeen days at sea, with a favorable wind and sailing with maximum speed and ease, we reached the land of China."
*The Delhi Sultanate was a Muslim state in northern India that was ruled by a Turkic elite.
