Creating a law to restrict the personal use of cars and requiring everyone to use public transportation would be as unthinkable as revising the laws of gravity. There are some forces so fundamental that we have no control over them.

What makes this analogy unsound?
A. Societies do have control over the laws they make.
B. Controlling personal car use takes minimal effort.
C.Rules and laws always have some exceptions.

B. Controlling personal car use takes minimal effort.

This statement is unsound because controlling personal car use does require effort and can be done through various means such as implementing regulations, providing efficient and affordable public transportation alternatives, and promoting sustainable transportation options.
