Which of the following is the correct expression for the Capital Market Line?

hat$(r{)}_p=r_{RF}+[\frac{\text{h}\text{a}\text{t}(r{)}_M-r_{RF}}{{}_M}].$

hat$(r{)}_p=r_{RF}+[\frac{\text{h}\text{a}\text{t}(r{)}_M-r_{RF}}{{}_M}]{}_p.$

hat$(r{)}_p=[\frac{\text{h}\text{a}\text{t}(r{)}_M-r_{RF}}{{}_M}]{}_p.$
