B) Develop a histogram of the residuals.

Both developing a normal probability plot of the residuals and developing a histogram of the residuals are commonly used methods to assess whether the regression model meets the assumption of having normally distributed residuals. The normal probability plot can provide a visual display of whether the residuals are normally distributed, while the histogram can show the shape and skewness of the distribution of the residuals. Therefore, the best choice is D.
