Solution
The correct option is B 20 minutes Walk = 37 minutes
37 minutes can be rounded off to 40 minutes
Taxi = 18 minutes
18 minutes can be rounded off to 20 minutes
Total duration= 82 minutes
82 minutes can be rounded off to 80 minutes
So as per the question
Walk + Taxi + Bus = 80 minutes
40+20+Bus = 80
Bus = 20 minutes
