Explanation / Answer

Correct statement: The regression model does deal well with the two types of pizza because all the residuals show distinct patterns with two different slopes for each type.

Explanation: The residual plot shows that there are distinct pattern for each type of pizzas Cheese and Pepperoni hence the regression model will predict according to type of pizza.

First option is incorrect because there is nothing to do with the combined residuals if we are predicting for type of pizza, it will consider the pattern of residuals according to the type of pizza. And other option are incorrect beacuse adjusted R square value = 0.581 which is neither high or low.
