Beta is a measure of market risk
Lowest beta is of Makissi Corp., hence it contributes lowest to market risk
Stand alone risk is measured by Standard Deviation
Hence, the answer is Kulatsu Motors Co. (KMC)
Portfolio beta is equal to weighted average beta
= 1*3500/10,000 + 1.50*2000/10,000 + 1.10*1500/10,000 + 0.50*3000/10,000
= 0.965
Required return = Risk free rate + beta*market risk premium
= 7% + 0.965*8.5%
= 15.2025%
