Common Data: A line source and a line sink, both of unit strength, are placed on the $x$-axis at $x = -1$ and $x = +1$ respectively. In terms of the Cartesian unit vectors $\mathbf{i}$ and $\mathbf{j}$, the velocity at the point $(0,1)$ is given as
- A. $0\mathbf{i} + 0\mathbf{j}$
- B. $\frac{1}{2\pi}\mathbf{i}$
- C. $\frac{1}{2\pi}\mathbf{j}$
- D. $\frac{1}{\pi}\mathbf{i}$
