选项 A、only unsystematic risk, while standard deviation measures total risk
B、only systematic risk, while standard deviation measures total risk
C、both systematic and unsystematic risk, while standard deviation measures only unsystematic risk
D、both systematic and unsystematic risk, while standard deviation measures only systematic risk

解析 答案为B项。贝塔和标准差都可以用来衡量风险的火小,其小同之处在于贝塔衡量的只是系统风险,而标准差衡量的是总风险。故本题选B项。
