B; But cycling is a bit too slow, it takes u about 40 mins to reach office, while it only takes me 15 mins.

A: Yes, I agree, time is not a matter for me, at least I saved my time to go to gym, and cycling does not make any pollution to the air. It is environment friendly

B: Ohh, yeah, that's the point, but I will would prefer to take car any way, sitting in car prevents you from breathing polluted air outside, isnt it?
