Question

who actively protected the trade routes even thought they were known for attacking and stealing from others? mongols persians chinese greeks

Explanation:

The Mongols, while known for their military conquests and raids, also established a vast empire that facilitated trade along the Silk Road by providing security for trade routes. They maintained law and order (the Pax Mongolica) which allowed safe passage of merchants, despite their reputation for attacking and plundering in other contexts. Persians, Chinese, and Greeks had different roles in trade route protection and didn't have the same dual reputation of attacking and protecting trade routes as the Mongols.

Answer:

A. Mongols
