The correct answer is A) Increased trade along China's eastern coast.

The development of hybrid plant species and advances in irrigation methods led to this effect during the Tang dynasty: Increased trade along China's eastern coast.

During the Tang Dynasty, irrigation advances played a key role to farm the lands and produce quality crops that were traded with other regions. In particular, the peaceful times during the Tang Dynasty allowed Chinese farmers to focus on producing crops that were important for the Dynasty as was the case of rice. Agriculture became stronger with irrigation techniques when farmers started to grow tea. Emperors were very proud of agriculture, made great profits and this also was a symbol of power.

the arab empire adopted the muslim religion as their main belief. arabs would influence the people from the territories they invaded towards islam (the muslim belief).

nevertheless, throughout the history of the arab empire, rulers brought intellectual individuals from other religions to their centers of learning. these other foreigners included jews, christians, greeks, persians, and indians.   these resulted in the adoption of important knowledge developed by these cultures by the arabic empire. for example, the works of aristotle were translated from greek to arab and indian scientists brought the numerical concept of "zero" to the arabs.

nowadays, 93% of the arab population is muslim, which at the same time is subdivided in sects including the sunni, zaini, alawi, shia. the remaining 7% is composed mainly of christians.
