The correct answer is: A. receive in future.
An expected rate of return is the rate of return that an investor expects to earn on an investment over a given period of time. It is calculated by taking into account the expected future cash flows from the investment and the time value of money.
Option B is incorrect because the expected rate of return is not the rate of return that the investor has already received. It is the rate of return that the investor expects to receive in the future.
Option C is incorrect because the expected rate of return is not the yearly growth of the investment. It is the rate of return that the investor expects to earn on the investment over a given period of time, which may be more or less than one year.
Option D is incorrect because the expected rate of return is not the semi-annual growth of the investment. It is the rate of return that the investor expects to earn on the investment over a given period of time, which may be more or less than six months.
