Answer: C) The sisters are envious that Ma Sogolon gave birth to a healthy boy.
Explanation:
When the Mande women heard that Ma Sogolon had given birth to a boy who had survived and was healthy, they gathered together and bemoaned the fact that Ma Sogolon not only gave birth to a boy, but that the boy had also survived.
They then used sorcery on the boy to make him confined to the ground. This shows that they were so envious of Ma Sogolon such that they plotted and took the boy's ability to walk.
