• A) Capital is significant in explaining corporate sales and should be included in the model because its p-value is less than 0.01.
• B) Capital is significant in explaining corporate sales and should be included in the model because its p-value is more than 0.01.
• C) Capital is not significant in explaining corporate sales and should not be included in the model because its p-value is less than 0.01.
