Concept:An argument is strong if it directly relates to public welfare, health, or safety without ignoring the rights of others.
Explanation:Argument I says that banning smoking protects non-smokers from secondhand smoke.
Secondhand smoke is a known health risk, and non-smokers in public places are exposed to it without their consent.
Therefore, protecting public health is a valid and strong reason for a ban.
Argument II says that banning smoking infringes on individual freedom and personal choice.
However, personal freedom does not include the right to harm others.
When smoking in public affects the health of others, individual choice cannot be treated as an absolute right.
Hence, Argument II is weak.
Answer:A. if only argument I is strong
