A) The histogram of the residuals should be approximately bell-shaped because it indicates that the residuals are normally distributed.
B) The scatter plot of the residuals against the dependent variable should illustrate homoscedasticity, which means the variability of residuals is constant across all levels of the dependent variable. 
Therefore, both A and B are true, indicating that the simple regression analysis satisfies the regression assumptions.
