Final Answer : A, Explanation :  Option A is the correct choice because it represents a linear regression equation that likely fits the given data, where the intercept (11291) represents the estimated price when the age is 0, and the slope (-1578) indicates the decrease in price for each additional year of age. This choice is reasonable given the pattern of decreasing prices with increasing age in the provided data.
