I think that your answer choice is correct because Ford did not want his cars to be expensive. He wanted them to be affordable for all people. Also, he did not invent the assembly line.
I believe the answer you chose is the correct one.
Filial Piety was an idea in Confucian philosophy where elders were meant to be respected the most.
It is something that is still held to majority of Asian society in which the children of the family would respect the elders the most, for instance, the grandchild and the grandmother would have the grandmother respected the most and so on throughout the family tree.
Hope this helps!
