Finance problem thx!

A company is going public today. It announces that it plans to pay dividends of $1 per share exactly three years from now and $2 per share exactly four years from now. From year 5 onwards, dividends are expected to grow at a constant rate of 10% per year. The company pays no dividends in years one and two. The risk-free rate is 5%, the company's beta is 1.5 and the expected return on the market is 11%. At year 4, after paying its dividend, we see that the company is trading in the stock market at $80 per share. At that point in time, what is the constant growth rate that the market is attributing to that company? Assume that all earnings are paid as dividends (that is, b=0). (1 POINT) A. 11.2195% B. 12% C. 12.1195% D. 14%
