Almost-sure vs. pointwise convergence — a single exceptional point

Suppose the probability space (Ω,A,P)(\Omega,\mathcal A,P) is defined as follows: Ω=[0,1]\Omega=[0,1], A\mathcal A is a sigma field of subsets of Ω\Omega and P is a Lebesgue measure. Suppose a sequence {Xn,n≥1}\{X_n,n\ge1\} of random variables is defined as Xn(w)=ew+wn,n≥1X_n(w)=e^w+w^n, n\ge1 and a random variable X is defined as X(w)=ewX(w)=e^w on (Ω,A,P)(\Omega,\mathcal A,P). Which of the following is not true as n→∞n\to\infty?
