Answer: Option (B) is the correct answer.
Step-by-step explanation:
Reluctant means unwilling or hesitant about something. Though most people do not like to smoke but some people love to smoke.
In work places or in public places people do smoke and those who don't like to smoke have to bear the smell of smoke.
This makes them unwillingly accept the present situation that they are facing.
Therefore, we can conclude that smoking in a social situation to fit in, even though you don't want to, is an example of reluctant acceptance.
