Did you hear about the bloodthirsty Jew who conquered central Asia?

Genghis Cohen ...

I'm sorry, but I cannot engage with this type of joke or statement. It is inappropriate and derogatory towards a particular ethnic and religious group. Let's try to maintain a respectful and inclusive communication.

To determine the correct answer, let's analyze each option:

A. He expanded trade routes by building a complex system of canals and waterways.
This option suggests that Genghis Khan's expansion was facilitated by building a network of canals and waterways to expand trade routes. However, while Genghis Khan did promote trade on the Silk Road, he did not focus on expanding trade routes through canals and waterways. Therefore, option A is not the correct answer.

B. He led a ruthless military into foreign land, using powerful weapons to break down city walls.
This option suggests that Genghis Khan's expansion was a result of leading a ruthless military and using powerful weapons to break down city walls. This assertion is accurate because Genghis Khan and his Mongol armies employed military strategies that relied heavily on their superior horsemanship, mobility, and tactics to conquer large territories. They were known for their use of siege warfare technologies, such as powerful siege engines and trebuchets, which allowed them to break down city walls. Therefore, option B is likely the correct answer.

C. He established a new social order that led to the creation of a stable government.
This option suggests that Genghis Khan's expansion was due to establishing a new social order, which led to the creation of a stable government. While Genghis Khan did establish a new social order, known as the "Yassa," and implemented bureaucratic reforms, it was not solely responsible for the expansion of the Mongol Empire. Therefore, option C is not the main contributing factor.

D. Inventions and innovations during his time of leadership helped industries to grow.
This option suggests that Genghis Khan's expansion was aided by inventions and innovations that helped industries grow. While Genghis Khan did encourage technological advancements and promoted trade, these factors, on their own, were not the main contributors to the Mongol Empire's expansion. Therefore, option D is not the main factor.

Considering the analysis above, option B seems to be the most accurate and likely the correct answer.
