\(\mathbf{R}\) is a closed planar region as shown by the shaded area in the figure below. Its boundary \(C\) consists of the circles \(C_1\) and \(C_2\).
If \(F_1(x,y), F_2(x,y), \frac{\partial F_1}{\partial y}\) and \(\frac{\partial F_2}{\partial x}\) are all continuous everywhere in \(\mathbf{R}\), Green’s theorem states that \(\iint_R \left( \frac{\partial F_2}{\partial x} - \frac{\partial F_1}{\partial y} \right) dxdy = \oint_C (F_1 dx + F_2 dy)\). Which ONE of the following alternatives CORRECTLY depicts the direction of integration along \(C\)?
