a study shows that commuters in chicago prefer to ride a bike to work.

Explanation:

To find the evidence for the claim that bike sharing eases traffic burden, we analyze each option:

• Option 1: Chicago commuters' bike preference doesn't directly relate to traffic burden reduction.
• Option 2: The addition of bike lanes improving car travel time shows that bike - related infrastructure (which bike sharing is part of in terms of reducing car reliance) eases traffic burden as improved car travel time implies less congestion.
• Option 3: Lower stress levels from biking is about mental health, not traffic.

Answer:

B. A study shows that the addition of bike lanes improved travel time by car.
