We can use the formula W=mg, where W is weight, m is mass, and g is acceleration due to gravity. On Earth, g is approximately 9.81 m/s^2. So, on Earth, we have W=mg=(834 N)/(9.81 m/s^2)≈85 kg. On Mars, the acceleration due to gravity is approximately 3.71 m/s^2. So, on Mars, we have W=mg=(85 kg)(3.71 m/s^2)≈316 N. Therefore, the answer is B.
