We can use the learning curve formula: Y = aX^b, where Y is the time it takes to produce a unit, X is the number of units produced, a is the time required for the first unit, and b is the learning rate (in decimal form). 
Plugging in the given values, we get: Y = 832 * (10^0.301) ≈ 315.6 hours. Therefore, the answer is D) from 301 to 325 hours.
