You have to choose answer b, because
(\int_{a}^{b}f(x)dx=\frac{b-a}{2}\int_{-1}^{1}f(\frac{b-a}{2}x + \frac{b-a}{2})dx=\frac{b-a}{2}\sum_{k=1}^{n}\omega_{k}f(\frac{b-a}{2}x_{k} + \frac{b-a}{2}))
(\int_{a}^{b}f(x)dx=\frac{b-a}{2}\int_{-1}^{1}f(\frac{b-a}{2}x + \frac{b-a}{2})dx=\frac{b-a}{2}\sum_{k=1}^{n}\omega_{k}f(\frac{b-a}{2}x_{k} + \frac{b-a}{2}))
