The corporation is a multidivisional conglomerate. The food division is undergoing a capital budget analysis and must estimate the divisions beta. This division has a different level of systematic risk than is typical for Corporation as a whole. The most appropriate method for estimating this beta is:
a. the regression coefficient from a time series regression of food divisions return on assets on a market index
b. the regression coefficient from a time series regression of corporation stock returns on a market index
c. To multiply the companys beta by the ratio of the food divisions total assets/corporation total assets
d. the regression coefficient from a time series regression of food divisions net income on the corporations return of assets
