For (x ^ x + y ^ y), find the integral on the forward curve enclosed by y = x and y = x ^ x. The statement is correct:

A、symsx;y=x;f=(x^2+y^2);I1=path_integral(f,[x,y],y,0,1)y=x^2;f=(x^2+y^2);I2=path_integral(f,[x,y],x,1,1),I=I1+I2;
B、symsx;y=x;f=(x^2+y^2);I1=path_integral(f,[x,y],x,1,0)y=x^2;f=(x^2+y^2);I2=path_integral(f,[x,y],x,0,1),I=I1+I2;
C、symsx;y=x;f=(x^2+y^2);I1=path_integral(f,[x,y],x,0,1)y=x^2;f=(x^2+y^2);I2=path_integral(f,[x,y],x,1,1),I=I1+I2;
D、symsx;y=x^2;f=(x^2+y^2);I1=path_integral(f,[x,y],x,0,1)y=x;f=(x^2+y^2);I2=path_integral(f,[x,y],x,1,1),I=I1+I2
