c it has re - routed to force people to follow the communist government
d the yellow river became dry after construction of the three gorges dam.

Explanation:

The nickname "China's Sorrow" for the Huang He River (Yellow River) is mainly due to its history of severe flooding. Over time, these floods have led to massive human casualties and property damage. Option A is incorrect as the Communist Revolution in 1949 was not centered around the river in a way that would give it this nickname. Option C is not a valid reason as the river's course changes were natural or due to engineering for flood control, not to force people to follow a government. Option D is wrong because the Three Gorges Dam is on the Yangtze River, not the Yellow River.

Answer:

B. Flooding has caused massive human and property loss over time.
