Answer:
B. White or light clothes because of the heat
Step-by-step explanation:
A trans-Saharan journey begins from the Sahara to reach sub-Saharan Africa and North Africa. In the 8th to the 17th century, the Tran-Saharan route was taken to trade goods from Africa to Europe. In the early period, the trade route assisted in transporting slaves and food to different places.
It is recommended that to take a journey one must wear white or light clothes because of the heat. As the temperature is very high in the Saharan region it is preferable to wear light colours because they reflect heat which helps our body to keep cool.
