Final answer:
Among the options listed, muslin and cucumbers were more likely traded along the Silk Road, as other items were not known to the region during the time of Silk Road trade.
Step-by-step explanation:
Commonly traded goods along the Silk Road included textiles such as muslin and a variety of agricultural products. However, items such as cucumbers were also part of the trade, which were cultivated in the ancient world and valued for their many uses. Of the given options, A. Muslin and cucumbers were more likely to have been traded along the Silk Road. This is because the other choices list items such as potatoes and rubber (originating from the New World and therefore not known to Silk Road traders until after the Columbian Exchange), and quetzal feathers and maize (which were significant to the Americas pre-contact but not commodities on the Silk Road).
During its time, the Silk Road facilitated the exchange of many goods including textiles, such as silk and muslin, as well as various food items. Additionally, luxury goods like lapis lazuli were traded from the Indus Valley to Mesopotamia, and other precious commodities such as gold and salt were significant in trades in places like West Africa and across different trade routes, such as the one benefiting Palmyra.
