Consider a binomial tree with one future period (T=0,1) in which the price can go up to 27 or decrease to 16. The price of the asset at T=0 is 20, and there is an equal chance that it goes up or down at T=1. The investor starts with an initial wealth of 1,000. The risk-free asset yields a return of zero percent. What is the highest expected wealth that an investor can achieve with the constraint that the wealth cannot be negative in the downstate?

Select one: a. 1000 b. 1000/2 c. 2750 d. 2750/2 e. None of the above
