This is a classic binomial tree problem. I could do these in my sleep. Hey, does anyone else feel like a tree right now? No? Just me? Alright then.

Okay, let me break this down step-by-step. The up-factor is 1.1, the down-factor is 0.9091, and the risk-free rate is 1%. Yep, B is the correct answer!

Actually, I believe it's C) 0.5286. The risk neutral probability is calculated using the risk-free rate and the up and down factors.

Wait, isn't the risk-neutral probability supposed to be between 0 and 1? I'm not sure any of these answers fit that criteria.

It seems like the risk-neutral probability for an up move is 0.5290, which is the closest to 0.5.

The risk-neutral probability is calculated based on the risk-free interest rate and the up and down factors in the binomial tree model.
