B) randomly assign some people to a smoking condition and some others to a control condition.
C) compare the physical health of a heavy smoker to the physical health of a person who has never smoked.
D) teach one group of people to adopt good health habits and see if they are more likely to begin smoking than a group of people who have not been taught good health habits.

Final Answer :
B
Explanation :
To accurately determine the causal effect of smoking on physical health, an experimental study must control for other variables by randomly assigning participants to either a smoking or a non-smoking (control) condition. This method ensures that any differences observed between the groups can be attributed to the smoking itself, rather than to pre-existing differences between the groups.
