Based on the table of integrals, the integral of e^x^2 dx is equal to (sqrt(pi)/2)*erf(x). Therefore, the integral of e^(x^2-1) dx is equal to [(sqrt(pi)/2)*erf(x)]/2 evaluated from x=-1 to x=1. Simplifying this expression we get (sqrt(pi)/4)*[erf(1)-erf(-1)]. Since erf(-x)=-erf(x), we can simplify even further to get (sqrt(pi)/2)*erf(1). Therefore, the answer is B.
